As for the threats to law enforcement ... Shia reportedly told police, "I'll f*** you up."

Police came and arrested the actor and took him to the cop shop. Shia was charged with criminal trespass and disorderly conduct.

Shia pled not guilty Friday morning and left the courthouse a free man.

Shia LaBeouf looked like crap as he left the courthouse Friday ... after being arrested for essentially going insane inside Studio 54 in NYC.

Shia had remorse and hangover written all over his face as he walked away, just having pled not guilty to criminal trespass and disorderly conduct.

Shia allegedly threatened cops, yelled obscenities at patrons inside the club and disrupted the performance. He also gabbed an ass or 2 during his drunken tirade.

6:30 AM -- We've just obtained video of the incident ... shot by the neighbor, who says Justin was definitely trespassing on his property during the attack. The video is dark, but you can hear the neighbor yelling, "I see you. I f**king see you!"

Then Justin yells back, "F**k you! I got another one for you, actually!"

They keep yelling back and forth for about 30 seconds, until the neighbor tells his 13-year-old daughter -- who sounds terrified -- to call the cops.

By the way ... we're told Justin is now a suspect in a vandalism investigation. The police report calls it a misdemeanor, but the victim tells us the damage to his property far exceeds $400, which means this could easily become a FELONY.

Justin Bieber launched an all out egg assault on his neighbor's home Thursday night -- and the L.A. County Sheriff was called to the scene while the eggs were still flying ... this according to the alleged victim.

TMZ spoke to the neighbor who says he heard something banging against his house in Calabasas around 7:30 PM Thursday, and when he stepped on to a 2nd floor balcony ... he says he saw Justin down below hurling eggs at his front door.

According to the neighbor ... Bieber started aiming for him once he stepped onto the balcony and yelled, "What the Hell are you doing?"

Justin and the neighbor -- who've had previous run-ins -- also got into a verbal dispute while JB allegedly continued tossing a few more eggs at the house ... and then retreated back to his home.

The neighbor immediately called the Sheriff's Department -- and believes his house was pelted with no less than 20 eggs.

Law enforcement sources confirm deputies responded, and took an incident report from the neighbor. It's unclear, at this point, if they were able to speak to Justin.

Calls to Bieber's reps were not immediately returned.

Mark Wahlberg lashed last night, saying "For actors to sit there and talk about 'oh I went to SEAL training? I don't give a f**k what you did."

Wahlberg was speaking at the AFI Fest in L.A., when someone asked a question about the rigorous training for his movie, "Lone Survivor." It seems Mark may have had our story about Tom Cruise on his mind in which Tom seemed to compare his acting job to fighting in Afghanistan.

Wahlberg unloaded, saying "For somebody to sit there and say 'my job was as difficult as being in the military.' How f**king dare you, while you sit in a makeup chair for 2 hours."

Wahlberg didn't stop there. He said, "I don't give a s**t if you get your ass busted. You get to go home at the end of the day. You get to go to your hotel room. You get to order your f**king chicken."

As we reported, we have seen the video of Tom Cruise's deposition where he makes the Afghanistan reference. When the opposing lawyer says, "Now your counsel has publicly equated your absence from Suri for these extended periods of time as being analogous to someone fighting in Afghanistan," Cruise does not react -- he certainly doesn't make the question look like a joke.

In fact, when Cruise responds, "I didn't hear the Afghanistan, but that's what it feels like and certainly on this last movie it was brutal, it was brutal," he doesn't make it look like it's an obvious joke. It seems more like a macho answer.

But then, the opposing lawyer crystallizes the point and says, "Do you believe the situations are the same?" You can see a light bulb go off in Cruise's head, and he realizes where the lawyer is going, and he snaps, "Oh come on." At this point Cruise is disavowing any comparison.

2:04 PDT: Wahlberg's rep tells TMZ, Mark loves Tom and was in no way referencing him in his comments.

8:35 AM PT -- TMZ just spoke to the woman whose driveway Amanda built the fire on, and she tells us, she had no idea what was going on until cops knocked on her front door. She says cops asked her, "Do you know anyone by the name of Amanda Bynes, or why she would have some vendetta against you?" She said no ... not surprising because the woman is elderly.

Cops then described to her that there was a young lady in her driveway, who had lit a fire and was carrying a "little red gas tank." The homeowner says cops told her Amanda had burned part of her clothing.

Amanda Bynes is currently hospitalized on a 5150 hold ... after starting a small fire in the driveway of some random person's house Monday night, TMZ has learned.

Law enforcement sources tell us, the fire department responded to the home in Thousand Oaks, CA around 9pm -- near where Amanda was just accused of trespassing -- after someone noticed the small blaze in the driveway. The sheriff's department was subsequently called when Amanda was found standing near the campfire.

When sheriff's deputies arrived, they questioned Amanda about what she was doing, and why she was doing it -- and based on her answers, they determined she needed to be hospitalized on a 5150 hold. Translation: her answers were really wacky.

A 5150 hold is an involuntary hospitalization for mental evaluation. Amanda can only be held for 72 hours though.

Britney Spears was famously taken in on a 5150 in 2008 during her pre-conservatorship period.

And just to give you an idea of what Amanda looked like yesterday, these photos were taken at Bloomingdales in Santa Monica just hours before the hospitalization ... around 5pm.

Story developing ...

Amanda Bynes didn't just build a fire in a driveway Monday night ... she put a flaming cloth on top of a gas tank ... effectively creating a makeshift explosive -- this according to an eyewitness 911 call.

The caller describes it as a small fire -- a flaming cloth sitting on top of a gas tank in a residential driveway. He says the reason he called 911 is because of the gas tank ... i.e. the obvious possibility of a massive explosion.

The caller says he couldn't tell if the gas tank was full or not.

Thankfully, the gas tank did NOT explode -- but as we reported, the fire department rushed to the scene to extinguish the fire ... and sheriff's deputies placed Bynes on a 5150 psychiatric hold.

Cops confronted Amanda Bynes outside a retirement community after she got into an argument with a cab driver Sunday night ... TMZ has learned.

According to the cab driver ... Amanda was trying to get into an old folks home in Thousand Oaks -- outside L.A. -- when management at the place turned her away because they felt she was drunk and accused her of trespassing.

However, the retirement community was nice enough to call a taxi for Amanda -- but when she got into the cab she said ... "Get me the f**k out of here ... I don't have any money." Naturally, the driver kicked her out at that point.

We're told Amanda walked back toward the retirement community ... and that's when cops were called.

There's no record of Amanda getting arrested ... so, we're guessing she might have only been ticketed, possibly for trespassing.

Amanda grew up in Thousand Oaks -- and owns a house in nearby Calabasas.

The cab driver tells TMZ ... he was told Amanda was at the retirement village to visit a relative.

Amanda Bynes was arrested in her NYC apartment Thursday night for marijuana possession and throwing evidence out the window ... TMZ has learned.

According to law enforcement sources ... a building official called police after spotting Amanda in the lobby with a joint, acting erratically and talking to herself. We're told when cops arrived they knocked at her door and she let them in.

Our sources say when police saw the bong Amanda quickly tossed it out the window ... which fortunately didn't hit anyone on the street below.

Amanda, who was wearing a platinum blonde wig, was placed under arrest and went ballistic, yelling, "Don't you know who I am?"

She was booked for criminal possession of pot, as well as reckless endangerment and FELONY tampering with evidence.

Our law enforcement sources say Amanda was briefly taken to a hospital for psychiatric evaluation and then taken to the station for booking.

But the cop shop wasn't the last stop. A cuffed Amanda was then taken to night court just before midnight. She's still there in a holding cell, waiting for a judge. She should get a hearing sometime this AM.

Amanda's behavior has become increasingly bizarre over the past year -- with numerous arrests, a complete physical transformation and crazy tweets.
