POLAND — Maine game wardens say two snowmobilers were critically injured when their sleds collided in the town of Poland.

The Department of Inland Fisheries and Wildlife says 35-year-old Robert Bissonette of Auburn and 20-year-old Jared Murphy of Poland were riding together at about 7 p.m. Thursday, but they became separated.

Wardens say the collision occurred when Murphy went to check on Bissonette.

Both men were taken to the Central Maine Medical Center in Lewiston.

A witness told game wardens at least one of the snowmobiles was speeding.
