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

Police service representative Stacy Ball at the Van Nuys station says officers arrived at Sheen's Sherman Oaks home late Thursday afternoon and conducted a search for several hours that concluded around 10:30 p.m. She says officers retrieved one weapon, an antique gun.

Ball says such searches are routine in which a person is subject to a restraining order.

Authorities say Sheen was cooperative.

Sheen later tweeted the LAPD were "AWESOME. Absolute pros! they can protect and serve this Warlock anytime!!!"
