KALADAR, Ont. -- Police are investigating after a 53-year-old man was killed in an all-terrain vehicle crash north of Kaladar over the weekend.

Ontario Provincial Police say the incident took place on Saturday morning on a trail northwest of the township of Addington Highlands.

They say Krunoslav Segota, of Oakville, had been operating an ATV along the trail when he lost control of the vehicle on a curve.

Police say the ATV slid sideways and rolled over twice.

The man's 14-year-old son was following on a separate ATV and called a family friend for help.

An air ambulance took Segota to a hospital in Kingston, where he died of his injuries.
