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."
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.
