A teenager was in custody Wednesday after a fight outside of K Sandwiches in Linda Vista led to a shooting.
San Diego police say the 17-year-old suspect fired at least five shots into the restaurant at someone he had been in a fist fight with just before.
SDPD said the altercation involved students of Kearny High School and Mesa College.
Customers were inside the restaurant at the time of the shooting but no one was injured by the gunfire, police said.
"The amount of people who could have been injured in this shooting was incomprehensible," said Coedy Gilbert who lives in an apartment complex nearby. "It didn't matter if the crosswalk was off or on. They were running, they were bolting across the street. They had to get to safety. They were running through my complex they were running all up and down the streets."
Police say the teenager was found with a handgun in his possession and was arrested.
SDPD said the altercation does not appear to be gang-related.
