Charlie Sheen's Sherman Oaks, Calif. mansion was searched by Los Angeles police Thursday night.
At around 7:30 p.m., officers went to the home looking for firearms and ammunition. If found it would have put Sheen, 45, in violation of the temporary restraining order granted to his ex-wife, Brooke Mueller.
The search took just under three hours; Sheen was not arrested.
LAPD spokeswoman Norma Eisenman confirmed to UsMagazine.com, "We were there to investigate the possible violation of a restraining order. It came to our attention that Mr. Charlie Sheen is a registered owner of firearms so we were making sure there were no firearms or ammunition in the home."
On whether police found any guns in Sheen's home, "We are not releasing any findings. Mr. Sheen was very cooperative and the investigation is complete," she said. "We are done with it."
As news of the raid flooded the Internet, a source close to Sheen told Us, "Everything is fine. He knew this was coming."
During the search news helicopters captured footage of what appeared to be Sheen eating dinner in his backyard. Sheen also took to his Twitter and wrote, "All good here on homefront. All reports are false. I'll explain more very soon."
After police left he told fans, "The LAPD were AWESOME. Absolute pros! They can protect and serve this Warlock anytime!"
The visit came on the same day Sheen announced he was filing a $100 million dollar lawsuit against Warner Brothers and the creator of Two and a Half Men. He was fired from the show on Monday.
It is the second time police have visited Sheen's gated community in recent weeks. Ten days ago they retrieved his twin boys from his custody after Mueller was awarded the temporary restraining order.
