Four people were injured, one in critical condition, in a two vehicle crash in the city's south end Sunday afternoon.

Viewer video sent to CTV News shows a grey sedan speeding around a corner, crossing the median and appearing to crash head-on into another vehicle at Bank St. and Conroy Rd. The collision caused both vehicles to burst into flames.

A 24-year-old man sustained multi-system trauma and was taken to hospital in critical condition. Two other men from the same car, aged 24 and 31, sustained serious injuries.

The 58-year-old woman driving the other vehicle was also taken to hospital in serious but stable condition.

Bank St. was closed while police investigated. It re-opened just before 9:00 p.m. Sunday.
