BRIDGTON — Wildlife officials say a Massachusetts man suffered serious head injuries in an all-terrain vehicle accident in Maine.

Officials say 45-year-old William Sturgis of Waquoit, Mass., was injured shortly after 11 p.m. Saturday after rolling his ATV into a ditch alongside a driveway in Bridgton.

Wardens say alcohol was a factor and that Sturgis was not wearing a helmet.

He was taken to Central Maine Medical Center, where he was listed in serious but stable condition.
