A man was stabbed in Calgary’s Marlborough neighbourhood on Sunday.
Emergency crews responded to the Marlborough train station before 4 p.m., police said.
A man with “traumatic injuries” who was in serious, potentially life-threatening condition was taken to Foothills Medical Centre, EMS said.
Police said the stabbing happened on the stairs by the pedestrian overpass and they are now looking for four suspects.
Calgary Transit said the station was closed at 4 p.m. “until further notice,” adding that Blue Line shuttles would replace service between Franklin and Rundle stations.
