SAN DIEGO – Police released video of a suspect punching a woman downtown Monday night and asked the public to help identify him.

The suspect was arguing with his fiancée on the sidewalk near the intersection of 6th Avenue and C Street around 8:30 p.m., San Diego police Sgt. Dan Brinkerhoff said. A woman noticed the argument and confronted him.

“She was heard on the video saying she was calling 9-1-1,” Brinkerhoff said. “The suspect punched the victim in the face with his right hand.”

The woman, who is 5-feet, 5-inches tall and weighs 170 pounds, was hit twice and knocked over.

“He hit me with his two fists,” the victim is heard saying on another cell phone video.

After the attack, the man started yelling at bystanders and continued arguing with his fiancée.

The suspect left before police arrived. His fiancée stayed but refused to give his identity – even after repeated attempts by police to seek her help.

The suspect was described as a 6-feet, 2-inches-tall black man in his 50s and weighing 245 pounds. He was wearing a brown-colored suit with a cream-colored shirt.

Police say after releasing the video, tips poured in helping them identify a suspect.
