Gunfire crackled through parts of Minneapolis’ North Side late Thursday and into Friday, leaving three people wounded in separate shootings, police said.

The victims’ conditions weren’t known as of Friday.

Over several hours Thursday night, all of the precinct’s roughly dozen available squad cars were tied up with the shootings and a series of other emergencies — including a report of a baby not breathing — leaving some lower-priority calls backed up in the queue awaiting an available officer.

In the first reported shooting, around 10:12 p.m., a 33-year-old man was shot in the back in the area of N. 33rd and Fremont avenues, apparently by a motorist who got out of a vehicle and fired a high-powered rifle, a police report said. Before the shooting, witnesses reported hearing an argument between two groups of people near the intersection.

About 11:38 p.m., officers found a male gunshot victim, 31, who had been shot by a man believed to be his brother in the 1700 block of N. 26th Avenue in the Jordan neighborhood, the report said. The victim was treated for gunshot wounds to the legs, police said. Police said the suspect reportedly fled on foot, leading officers to search the area with the help of a police dog. He was arrested sometime later in the area of N. 25th and Logan avenues.

Department spokeswoman Sgt. Darcy Horn said a preliminary investigation suggested the shooting “may have been domestic-related.”

Just before 1 a.m. Friday, police responded to a reported shooting in the 4800 block of N. Aldrich Avenue in the Lind-Bohanon neighborhood. When they arrived, they found a 28-year-old man with a gunshot wound to the upper left thigh, police said. Officers interviewed several witnesses who were in a residence nearby where the shooting reportedly occurred but received only limited information about what happened, police said. They later returned with a warrant to search the residence for evidence, police said.

According to Horn, none the incidents appear to be connected.
