A family argument during a Thanksgiving Day dinner in San Francisco ended with a trip to the hospital after a 25-year-old man was stabbed with a kitchen knife, police said Monday.

It was one of at least two Thanksgiving dinners in the city that turned violent. In a separate incident in the Portola neighborhood, shots were fired but no one was injured.

The stabbing took place at the Parkmerced townhomes and apartments in the 400 block of Serrano Drive about 8 p.m. Thursday.

The suspect, a 28-year-old man, had been fighting with the victim before he grabbed a knife from the kitchen, stabbed him, then ran away, police said.

The victim was taken to a hospital with non-life-threatening injuries, police said. Authorities later found and arrested the suspect. His name was not immediately released.

Police did not elaborate on the relationship between the suspect and victim, but described the fight as a “family dispute.”

In the Portola incident, a 30-year-old man was arrested on suspicion of negligent discharge of a firearm. Police have not yet released his name.

The suspect was having dinner about 9:30 p.m. with two victims on the 700 block of Burrows Street when he showed them his gun. Both victims decided to leave because they “felt uncomfortable,” then the suspect pointed the gun at one victim before firing it into the air, police said.

The man fled but was later detained by police.
