The San Diego Police Department has released surveillance video in an attempt to catch the man seen beating a woman in the Gaslamp Quarter on Monday.
In the disturbing video, a man is seen punching a woman in the face two times as she falls to the ground.
The altercation happened at 8:30 p.m. on Monday near the intersection of 6th Avenue and E Street in the busy downtown area.
SDPD said the 50-year-old man was arguing with his fiancée when a woman approached them to intervene.
"She was heard on video saying she was calling 911," SDPD said.
That's when the suspect swung at the woman, striking her in the face with his right hand.
The man took off before SDPD arrived. His fiancée stayed at the scene but refused to cooperate with investigators, even giving them a false name, police said.
The suspect is described as standing 6 feet 2 inches and weighing 245 pounds. At the time of the altercation he was wearing a brown suit with a cream-colored shirt, SDPD said. The video shows him wearing a black hat and jewelry.
SDPD released the video after exhausting other leads, the department said. Hours after the video was shared, the agency said the identification of the suspect had been obtained but the man had not yet been arrested.
The District Attorney's office declined to press felony charges against the man but he is expected to face misdemeanor charges, SDPD said.
