LOS ANGELES (Reuters) - Police searched the home of Charlie Sheen on Thursday looking for firearms that would have violated a court order against him, but they found only bullets and an antique rifle, a lawyer for the actor said.

Los Angeles Police Department spokeswoman Officer Norma Eisenman said the search ended with no arrests being made.

"Mr. Sheen was very cooperative," she said.

The search was linked to a temporary restraining order filed against Sheen last week by his ex-wife, and it occurred on the same day the troubled actor filed a $100 million lawsuit against his former employers on the hit CBS sitcom "Two And A Half Men" claiming he was wrongfully fired this week.

Sheen had been the highest paid actor on U.S. TV in his leading role on the top-rated program, playing a hard-drinking, skirt-chasing bachelor loosely based on his own life.

Over the past year, Sheen has run into legal troubles and been in and out of rehab for drug and alcohol abuse. In the past several weeks, he has engaged in public rants against "Two And A Half Men" producer Chuck Lorre and Warner Bros. Television, which produces the show.

Last week, his ex-wife Brooke Mueller filed a temporary restraining order against Sheen to keep him away from their two children. Under that order, he was not allowed to possess firearms.

Outside Sheen's home on Thursday night an attorney for the actor, Mark Gross, told reporters an unidentified caller had phoned police with a tip that Sheen had a gun.

Gross said police found "a few bullets and an 1800s rifle" and Sheen thanked them "for being professional and courteous.

Officer Eisenman said police would not disclose what was uncovered in the search and no further details would be released.

Warner Bros. Television is a division of Time Warner Inc., and CBS is owned by CBS Corp..
