A 20-year-old man has been charged in connection with a suspicious death at Olympic Plaza, Calgary police said late Saturday night.

Officers were called to the 200 block of 8th Avenue S.E. at about 10:15 p.m. MT on Friday by a witness who said it looked like a man needed help.

EMS was called in about 15 minutes later for what was originally believed to be an assault.

A man was later declared dead at the scene.

Police took one man into custody and said they weren't looking for any other suspects. Late Saturday night, they charged him with second-degree murder.

An autopsy has been scheduled for Monday to determine the victim's cause of death.
