FBI Makes Arrest in Celebrity Phone-Hacking Case

The FBI has arrested one person suspected of hacking into the phones of Hollywood stars like Scarlett Johansson and Vanessa Hudgens ... and leaking private photos. And, we've learned, the FBI is convinced the guy is a lone wolf, who never got a cent for the pictures he stole ... he just did it for the thrill.

Law enforcement sources tell us the man is from Florida, and the FBI has known about him for several months, but the U.S. Attorney didn't take action until now.

Our sources say the man hacked into numerous celebrity phones and then distributed the ill-gotten photos to third parties, never asking for any money. He did it because he got a charge out of it.

The FBI says the investigation was dubbed, "Operation Hackerazzi."

So far, the identity of the suspect has not been released.
