Lambton County OPP officers say they have concluded their investigation after a man died while working on his farm.

Officers responded to an injury call Thursday afternoon in the 1200 block of Stanley Line in St. Clair Township, where they say a man was apparently wounded by a farming combine.

The OPP says their investigation revealed 79-year-old Walter Scott was discovered in distress by his son. He later succumbed to his injuries.

Following their investigation and an autopsy on Friday, OPP say no further police action is required.

The Ministry of Labour attended the scene and is also investigating the incident.
