Pauley Perrette tweeted that she "immediately drew a sketch of the guy" who allegedly violently attacked her outside her Hollywood, California home on Thursday -- and ET exclusively obtained the first look at her drawing.
The NCIS star recounted in a Twitter post early Friday morning that a "psychotic homeless man" came at her and started repeatedly punching her and threatening her life.
Once Perrette was able to get free, she texted a friend and a police officer from her church, who had her draw a sketch of her alleged attacker. She said the man was "headed towards Hollywood with murder in his eyes."
So, tonight was awful, life changing and I'm only grateful to be alive. It's here: pic.twitter.com/vXIT1pkVRc— Pauley Perrette (@PauleyP) November 13, 2015
"My pal James took a pic of the sketch, found the guy [and] surveilled him," the 46-year-old actress wrote. "The cops came and followed James to him. They got him. Felony assault."
Perrette's drawing, done in blue ink, is of a man with an unkempt beard and Western-style hat. He appears to be wearing a jacket in the sketch.
In a photo of the man police arrested, 45-year-old David Merck, he has a scraggly beard and a hat.
The LAPD confirmed Perrette's story and told ET they were contacted at 5:14 p.m. on Thursday. The police booked 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."
