A police officer used a tourniquet to stop the bleeding when a 20-year-old was shot in the arm in St. Paul’s North End, police said Wednesday.

A 60-year-old man flagged down an officer on Tuesday at 1:55 p.m. at Rice Street and Winnipeg Avenue and pointed down the block saying, “That guy just got shot,” according to a police report.

The officer found the 20-year-old a block away, at Rice and Atwater streets, where a friend was walking him back from the corner, said Steve Linders, a St. Paul police spokesman.

Paramedics took the young man to Regions Hospital with a non-life threatening injury.

A crowd of about 20 people gathered at the scene, but they “didn’t want to help or give information,” Linders said. No one had been arrested as of Wednesday.

In a search warrant filed Tuesday, police described a separate shooting over the weekend.

On Sunday, officers were dispatched to a shooting at Dale Street and University Avenue, where they found a pool of blood in the intersection.

Soon after, a silver Pontiac arrived at Regions with a passenger who shot in the forearm and abdomen, Linders said. He was taken into surgery and was reported to be in stable condition.

The driver said he didn’t know the injured man, but was driving on Dale Street when he saw a silver Pontiac stopped in the intersection and the driver was “slumped partially out of the vehicle and he stopped to check on him,” according to an application for a search warrant for the car. The man reported he got in, pushed the injured man into the passenger seat and drove him to the hospital.

The shooting came several hours after three people were shot and wounded outside a bar at Thomas Avenue and Grotto Street.
