A 20-year-old Winnipeg man has been charged with attempted murder after another man was attacked twice at a downtown parking lot on Monday night.

It happened in the 300 block of Ellice Avenue at around 10 p.m., police said.

"For reasons unknown, an intoxicated 20-year-old male confronted a 23-year-old male while in a nearby parking lot and proceeded to assault him in the upper body causing serious injuries," police said in a news release Tuesday.

Police said the suspect left the victim behind and tried to go back to a hotel in the area, but he wasn't allowed in because he was intoxicated, so he allegedly went back to the victim and attacked him again.

It was at the time of the second attack that emergency crews were called. The victim was taken to hospital and the suspect was arrested at the scene.
