An 18-year-old man has died in a Calgary hospital bed following a Heritage Day incident in a lake just north of Lethbridge.

On Monday afternoon, emergency crews were called to the shores of Park Lake after witnesses pulled an unconcious 18-year-old from the water. Officials believe the man had been in the water for roughly 10 minutes.

An EMS crew transported the 18-year-old to the Chinook Regional Hospital in Lethbridge where a STARS Air Ambulance crew accepted the patient and flew him to a hospital in Calgary.

On Tuesday, RCMP confirmed the unnamed man had passed away.

Police do not consider the man's death to be of a suspicious nature.
