NCIS actress Pauley Perrette, who plays the show's Goth crime lab tech Abby Scuito, had a real-life scare Thursday in Los Angeles. A "psychotic homeless man" jumped her on the street outside her home and punched her in the face several times.

"I almost died tonight," she wrote on Twitter. "Tonight was awful, life changing and I'm only grateful to be alive."

Perrette recounted the incident in detail in an essay, which she photographed and attached to her post. In it, she said the man kept telling her his name (William) and that he was going to kill her. In her essay, Perrette, who works with charities for the homeless, pleaded for housing and full mental health care for them.
