Police searched Charlie Sheen's house for possible firearms for about two and a half hours on Thursday night, and his lawyer later told TMZ that they recovered an antique gun and several bullets.
The search was prompted by a report that the "Two and a Half Men" star might own a gun or other firearm and ammunition, a possible violation of his restraining order from estranged wife Brooke Mueller, Norma Eisenman, a spokesperson for the Los Angeles Police Department told TheWrap.
Sheen's attorney, Mark Gross, told The Hollywood Reporter the search warrant "was issued as a result of somebody, some crack call" who claimed Sheen was in violation of the order. He said he did not believe it was Mueller, who obtained her temporary order last week.
The search started at somewhere between 7:30 and 7:45 p.m. and ended at roughly 10:20 p.m.
During the search, Sheen updated his Twitter page, telling fans there was nothing to worry about.
"#fastball: all good here on homefront. all reports are false. I'll explain more very soon. #Dogspeed c," the actor tweeted after reports broke of a police raid on his Sherman Oaks mansion.
He later added: ""#fastball; the LAPD were AWESOME. Absolute pros! they can protect and serve this Warlock anytime!!! c"
Eisenman said that Sheen is known to own firearms.
No arrests have been made and no charges have been brought, Eisenman said. She added that she did not know if any weapons had been found.
While the search was going on, Sheen apparently was at a table in the dining room, eating hamburgers with friends and his lawyers, TMZ said.
Sheen and Mueller are still trying to determine a custody agreement involving their two children.
Sheen was fired from his hit CBS sitcom earlier this week after a series of substance abuse related incidents and a very public dispute with "Two and a Half Men" creator Chuck Lorre.
He sued his former employers Thursday for $100 million and damages, saying Lorre's failure to produce scripts -- and not his own problems -- bear the blame for the show's shutdown for the season.
Warner Bros., which produces the show, has already successfully petitioned Judicial Arbitration and Mediation Services (JAMS) to have Sheen's lawsuit heard in that venue.
Before the search, Sheen had announced on Twitter that two dates would go on sale Saturday for his tour, which he called, "Fastball; My Violent Torpedo of Truth/Defeat is Not an Option Show." The first date is in Detroit on April 2, and the second in Chicago on April 3, according to Ticketmaster.
