“NCIS” actress Pauley Perrette tweeted Friday morning that she was assaulted overnight by a “Psychotic homeless man” who said he was going to kill her.

Perrette plays forensic scientist Abby Sciuto on the hit CBS show.

“He grabbed me so forcefully, pinned my arm, punched me in the nose, forehead repeatedly telling me he was going to kill me,” she tweeted.

“Then he showed me how he was going to kill me.”

“Some guy walked right past with a dog that licked my face. He was on his phone, annoyed. Did nothing,” she wrote.

Perrette reflected on her experience at the end of her note leaving the following message: “We need full mental health care. We need housing and help for the homeless. We need to support our cops. We need to not walk alone. I need to heal.”
