A man is in hospital after jumping from a ninth-floor Winnipeg apartment window to avoid police.

It happened at about 9:50 p.m. Sunday in the 300 block of Cumberland Avenue, where members of the Winnipeg Police Service's tactical unit were conducting a search for guns and drugs at an apartment suite.

Four men were being arrested when a fifth man jumped out a window and landed on the top of a parkade.

A man in the building next door heard the commotion.

“I happened to go and look out the window,” he said. “I saw a bunch of flash lights and cops all over the place, looking on the ground in between the cars.

Const. Jason Michalyshen said the roof of the parkade was on the third floor, meaning the man fell about six storeys from the apartment suite.

"As a result of that attempt to flee from officers … he fell from a significant height and unfortunately sustained some pretty serious injuries," Michalyshen told reporters on Monday.

"We're making every effort to identify who this individual is."

The man is currently listed in stable condition in hospital.

Police seized several guns, ammunition, crack cocaine and cash during the search.

All five men, between the ages of 18 and 26, are facing numerous drug and weapons charges.
