Los Angeles police searched actor Charlie Sheen's home Thursday night for guns that might be in violation of a temporary restraining order obtained last week by his estranged wife, Brooke Mueller.

Officers arrived at Sheen's home in the Sherman Oaks hills after informing his attorney. Sources said Sheen had guns registered to him that would be prohibited by Mueller's restraining order.

"We're doing our due-diligence," said a Police Department source connected with the case who asked not to be identified. LAPD officials said such weapon searches are routine in cases in which a person is subject to a restraining order.

Despite one report that Sheen might be taken for an involuntary psychiatric evaluation because of his recent erratic behavior, there was no indication that authorities planned to remove the actor from his home.

Authorities said Sheen was cooperative. There was no immediate information on how many, if any, weapons were taken from the home.

[Updated at 10:43 p.m.: The search of Sheen's house has concluded. Authorities are not releasing any information on what might have been found.

No one at the residence was arrested, an LAPD spokeswoman said. Sheen reportedly ate hamburgers as the officers searched the house.]
