Police released this mugshot of Austin James Vincent.
VIDEO: Woman attacked in front of home by man believed to be homeless
The 25-year-old was taken into custody after the terrifying incident.
In stunning video, you can see Paneez Kosarian trying to get through the front door of her building, when a man, believed to be homeless, grabs her, pulling her away from the door and onto the ground.
She struggles to get away, but eventually is able to crawl inside.
Kosarian's building is right next to the proposed site of the Embarcadero Safe Navigation Center. She's concerned things might be worse if it is built.
Police say when the center opens there will be additional security measures in place.
The group "Safe Embarcadero for All" is suing San Francisco to block it.
