Pauley Perrette, an actress best known for portraying forensics lab technician Abby Sciuto on NCIS, survived a horrifying assault by a homeless man near her Hollywood home earlier this week.

In the early morning of Friday, Nov. 13, the 46-year-old actress took to Twitter to share a screenshot of a lengthy word document in which she explained the scary attack. “Tonight was an awful night,” she began.

“I was walking across my street to a new guest house I bought to meet my architect… [when] I was jumped by a VERY psychotic homeless man,” Pauley continued. “He grabbed me so forcefully, pinned my arm, punched me in the nose [and] forehead, repeatedly telling me he was going to kill me.”

“There was an empty garage behind me and I knew if he got me in there I was dead. I knew I couldn’t overcome him,” she wrote. “He started to punch me again, and then said, ‘Get the f—k out of here’ And I did.”

After contacting the police, Pauley explained the authorities were able to arrest the man based off a police sketch she provided of her attacker. “They got him. Felony assault,” she wrote.

“I am shaken and traumatized… I almost died tonight,” Pauley added in her emotional tweet.
