A Massachusetts man was injured when his personal watercraft collided with one being ridden by his brother.

Corporal John MacDonald of the Maine Warden Service says the accident happened just after noon on Thursday. 33-year-old Alexander Chigas and his brother, 39-year-old Jason Chigas were riding separate Kawasaki personal watercrafts on Sebago Lake. The two vehicles collided and Alexander suffered a possible broken leg.

Wardens say both men were staying at their summer home on Jordan bay, on the lake's eastern shore. Speed is considered to have been a factor in the crash.

The Warden Service continues to investigate the incident
