Two suspects shot a man in the Bayview and then fled the scene on bus in the first of two unrelated shootings Monday in San Francisco, police said.

The Bayview attack happened around 2:20 p.m. on the 700 block of Phelps Street when a 26-year-old man stepped out of his van and got into a fight with two other men, police said.

That’s when one of the suspects, believed to be about 19 years old, shot the man in the arm, officials said.

The suspects took off running and hopped onto a nearby bus. The victim was treated at San Francisco General Hospital where he was recovering.

Around 10 p.m., officers in the Tenderloin heard gunfire coming from the area of Golden Gate Avenue and Jones Street. When police officers went to investigate, they discovered blood splatters and several shell casings on the street.

Later on, a 23-year-old man showed up at San Francisco General Hospital with gunshot wounds to his knee and elbow, police said. The victim, who was not identified, refused to provide information to police, officials said.

Police suspect two men in their 20s were responsible for the attack, but would not disclose further details.

No suspects have been identified in either shooting, which remain under investigation.
