A suspect fled and then later turned himself in after an assault left a man in life-threatening condition, Durham Regional Police say.
Police said officers responded to an unknown trouble call at a home on Cousins Street in Courtice, Ont., Thursday and found a 67-year-old victim suffering from obvious signs of trauma.
He was taken to a Toronto-area trauma centre and remains there in life-threatening condition, police said.
A suspect was quickly identified, but fled prior to police arriving, officers said.
Police then issued a public appeal to find him and soon after, he turned himself in, police said.
The suspect and the victim are known to one another, police said.
What may have led up to the incident is unclear.
A 22-year-old man from Clarington is now facing a charge of aggravated assault.
