NCIS star Pauley Perrette is claiming she had another scary moment with a male vagrant in Los Angeles on Tuesday.

The 46-year-old actress tweeted about the event early Wednesday morning, writing that a "homeless guy" grabbed her wrist and "put his whole head inside [her] car" when she offered him a dollar bill while stopped at a light.

"He held my arm and then said, 'What time is it?'" Perrette tweeted. "He was in my car and I was scared. I looked at my dashboard and first said, 'I rebuke you, Satan, in the name of Jesus Christ!' Then said to him, 'It's 5:37.'"

According to Perrette, the man released her arm soon thereafter and left.

Perrette added that even though she carries a tactical knife and taser in her car, she didn't think to arm herself, as her first concern was to cater to the man.

"I am learning," Perrette wrote. "I need to know both sides: be smart and be safe and give -- but all of them at once. Be smart and safe. I am learning."

An ET source who saw the man after his encounter with Perrette says that he was also aggressive with someone in an SUV who offered to help him, but ran away after the person gave him money.

This follows the incident on Nov. 13, during which Perrette says she was punched repeatedly and had her life threatened by a "psychotic homeless man." After she escaped, Perrette drew a sketch of the man she believed assaulted her and the Los Angeles Police Department later booked a 45-year-old white male suspect named David Merck on felony battery charges.
