A two-vehicle crash in northeast Calgary resulted in one man suffering potentially life-threatening injuries.
The crash happened just before midnight Friday at the intersection of 24 Avenue at 23 Street northeast, just west of Barlow Trail.
Police say two people were taken to hospital.
The male driver of one vehicle was taken to Foothills Medical Centre with serious potentially life-threatening injuries.
The other driver, an elderly female, was taken to the Peter Lougheed Centre with minor injuries.
The Calgary Police Service Traffic Unit had the area closed as part of their investigation, but the intersection re-opened at around 5 a.m.
