Shootings on Saturday and Sunday injured four people in three separate incidents in Winnipeg's North End and Centennial neighbourhoods, police say.

Officers called to Isabel Street near Bannatyne Avenue at around 6:30 a.m. Saturday found a man with a gunshot wound to the upper body.

Paramedics took him to hospital in critical condition and later he was upgraded to stable.

In a second incident not far from the first, officers were called to Elgin Avenue after a report of shots fired around 3 a.m. Sunday. The officers found two men with gunshot wounds to the upper body.

One man was taken to hospital in stable condition and later released, while the other was treated at the scene.

The third incident happened around 8:30 p.m. Sunday. Officers were sent to the 400 block of Boyd Avenue in the North End after a report of a male shot was received.

They found a man with a gunshot wound to his lower body. Paramedics rushed him to hospital in critical condition but he was later upgraded to stable.

His wound was "extensive but not life threatening," police said.

Police have not yet identified any suspects in any of the incidents.

"These are very new investigations and with a busy weekend, you can see that officers haven't had a whole lot of time to get into the details there," said Const. Tammy Skrabek.

Although police often see an uptick in shootings during the summer, Skrabek said the number of injuries within a short span of time and the fact that some happened on the street and during the daytime prompted police to speak out.

"It is unfortunate that we are seeing more in the daytime hours and more random, on-the-street-type shootings," she said.

It hasn't been determined whether any of the incidents were gang-related, Skrabek said.

The Winnipeg Police Service asks witnesses or anyone with information to call the major crimes unit at 204-986-6219 or contact Crime Stoppers.
