Sarnia police now say a man found at the intersection of Vidal Street S. and Clifford Street with an ATV nearby was intentionally killed.

Police arrested a man Saturday around 8 a.m. in connection with the death of 42-year-old Raynold Fisher of Sarnia.

Police were called to the scene of a single-vehicle ATV crash at 10:30 p.m. on Wednesday. They said at the time that a man was ejected from the vehicle.

Fisher was airlifted to a London hospital and died 24 hours later.

Insp. Norm Hansen says the man in custody has not formally been charged but is facing a first-degree murder charge.

"We are investigating constantly with our traffic (division)," he said. "(Fisher) was found near an unmanned ATV. Information that came forward led us in a different path. We interviewed a number of people and that led to the arrest."

The man in custody is awaiting a bail hearing.

Police continue to investigate and are asking anyone with information to call them at 519-344-8861.
