"I was walking across my street to a new guest house I bought to meet my architect. On my street, I was jumped by a VERY psychotic homeless man," she recalled. "He grabbed me forcefully, pinned my arm, punched me in the nose, forehead, repeatedly telling me he was going to kill me. Then he showed me how he was going to kill me."
The actress said the man kept repeating a name, William, and in attempt to calm him down, she said, "William is a beautiful name. I have a nephew named William."
The LAPD confirmed Perrette's story and told ET they were contacted at 5:14 p.m. on Thursday. The police booked a 45-year-old white male suspect named David Merck on felony battery charges after arresting him at a Hollywood 7-Eleven around 6 p.m. He is still in custody and bail is set at $100,000.
"I am shaken and traumatized," she said in her Twitter message. "My house, my beloved Hollywood. My beloved homeless people that I spend my life protecting. ...My life changed tonight."
She then insisted that "we need full mental health care" and "housing and help for the homeless."
