Two women suffered serious head injuries after a single vehicle crash in Owen Sound.
Police say a vehicle mounted a curb and hit a tree at 13th Street A West and 4th Avenue West early Saturday morning.
A 22 year old Owen Sound woman was airlifted to a London hospital with serious head and spinal injuries — but she has since returned home.
A 20 year old woman — also from Owen Sound — remains in the Owen Sound hospital with head injuries.
Police believe alcohol was a contributing factor in the accident.
Anyone with information with respect to the cause of the crash is asked to call Owen Sound Police.
