San Francisco police are investigating three separate unsolved shootings that have occurred in the city since Friday, including one in North Beach that left a 27-year-old man with a bullet wound to his buttocks.

The North Beach shooting happened just after 2 a.m. Saturday at the busy intersection of Broadway and Columbus Avenue, police said Tuesday. The victim, whose name was not released, told officers he was standing at the intersection when he realized he had been shot in the buttocks.

He was taken to San Francisco General Hospital and treated for non-life-threatening injuries, police said. No arrests have been made in the case.

In an unrelated shooting, a 25-year-old man was grazed in the head by a bullet at a Mission District playground, police said. The shooting happened just before noon Friday at the James Rolph Jr. Playground at 26th and Hampshire streets, police said.

The victim, who was also treated at San Francisco General Hospital, told police he was waiting for someone at the playground when a gunman approached him and opened fire. He said the suspect, described as about 20 years old, and another man fled the scene in a dark-colored sedan. No arrests had been made in the case as of Tuesday.

The third shooting occurred around 9:30 p.m. Friday at Third Street and LaSalle Avenue in the city’s Bayview District. The victim, whose age and name were not released, suffered a gunshot wound to the leg. Police said he was uncooperative and refused to provide information about the shooting.
