A Salem man faces several charges after a 4-year-old girl – who was not wearing a helmet – was injured in a snowmobile accident.

Salem police said Robert Frost, 28, was giving the child a ride on a snowmobile during the afternoon of Tuesday, Feb. 10, when she grabbed the throttle and he lost control of the vehicle and hit a tree.

Police officers, who responded to the Hess gas station on Route 28 after being notified of the accident, believe it occurred in the woods behind Millville Lake Dam.

Both Frost and the girl were thrown from the snowmobile. The girl suffered a head injury and was bleeding from several areas. Frost carried her out of the woods and attempted to drive her to a hospital, according to police. When the girl began to “act weird,” Frost pulled over and called for help. Emergency workers from the Salem Fire Department transported her to Holy Family Hospital in Methuen, Mass. Her injuries appeared to be non-life threatening, according to officials.

The snowmobile was in the back yard of Frost’s home when police responded to the accident. The vehicle had front-end damage and only one helmet was near it. Their investigation determined that the girl, the daughter of Frost’s girlfriend, had not been wearing a helmet when the accident occurred, according to police.

The New Hampshire Department of Fish and Game was notified and took over the investigation. According to Salem police Capt. Shawn Patten, Frost was charged with having an unregistered snowmobile, riding on private property without permission and for not having a helmet on the girl.
