Warrant Executed in Gilbert Arenas Gun Case

TMZ has learned the D.C. police -- with the help of cops in Arlington County, Virginia -- have executed a search warrant this morning at the home of Javaris Crittenton -- looking for the gun that may have been secretly wheeled out of the Washington Wizards locker room in a laundry basket.

Law enforcement tells us after Javaris and Gilbert Arenas drew guns on each other during a Christmas Eve standoff, witnesses believe they saw Javaris throw his gun into a laundry basket and someone from the organization wheeled it out.

We know there was surveillance video of people coming out of the locker room and cops are looking to see if they can spot the person who was pushing the cart.

Nevertheless, cops convinced a judge they had probable cause to search Crittenton's home -- we don't know if they found the gun.
