Los Angeles police have confirmed that officers went to Sheen's Sherman Oaks home.
Van Nuys station officials say officers went to Sheen's home Thursday night, but it's not known why they were there.
Sheen tweeted "all good here on homefront."
Meanwhile, attorneys for Charlie Sheen and his estranged wife say the former couple have reached an agreement that settles any custody issues and will end her pursuit of a lengthy restraining order.
Attorneys for Sheen and Brooke Mueller issued a statement Thursday night saying the pair had "reached an agreement that resolves their differences." The statement said the details of the arrangement were being kept confidential for the benefit of their twin sons.
Mueller obtained a temporary restraining order against Sheen earlier this month, claiming he threatened her on a recent trip to the Bahamas. A hearing had been scheduled for March 22.
Also on Thursday, Charlie Sheen filed a lawsuit against Warner Bros. and the executive producer of "Two and a Half Men" for $100 million.
The lawsuit alleges production was halted on the CBS sitcom to punish Sheen.
Warner Bros. Television had put the show on hiatus to allow Sheen time to seek therapy, then halted production for the season after Sheen launched tirades at executive producer Chuck Lorre. Sheen was fired from "Two and a Half Men" this week, leaving the top-rated sitcom's future in doubt.
Sheen's lawsuit alleges that Warner Bros. bowed to Lorre's desire to punish Sheen, and that the producer and Warners conspired to blame the actor for causing production to stop.
The suit also was filed on behalf of the sitcom's crew, which was put out of work.
Warner Bros. declined to comment on the suit.
