Surrey RCMP say an investigation is underway into the death of an injured man who was found unresponsive Tuesday morning in a vehicle with the engine still running.

Police said at around 9:25 a.m. on Tuesday, they received a report of a person passed out in a vehicle in the 8800 block of 127 Street. Despite life-saving efforts from first responders, the man did not survive.

"Criminality is believed to be a factor. Therefore, the Integrated Homicide Investigation Team (IHIT) has been deployed and will be working in partnership with the Surrey RCMP," Cpl. Vanessa Munn said in a statement.

The area surrounding the scene will be cordoned off for a "significant amount of time," and traffic in the area will be rerouted, police said.

Anyone with information about the incident is asked to contact IHIT at 1-877-551-4448.
