Police say the two motorcyclists injured Wednesday are brothers and were not wearing helmets when they crashed in Brunswick.

Nathan Kane, 30 and Joshua Kane, 22, both of Harpswell, were each riding motorcycles in the same direction, and witnesses said they were going very fast when the crash happened, police said.

Nathan Kane was listed in critical condition Wednesday night at Maine Medical Center in Portland. His condition Thursday was not immediately available.

Police said Joshua Kane was initially described as having an incapacitating head injury, but there was no information that he was taken by ambulance from the scene.

Nathan Kane was traveling at a high rate of speed and closing in on a line of traffic when he lost control and slid to a stop in the vicinity of the Brunswick Town Commons, a town-owned park off Harpswell Road, which is also known as Route 123.

Joshua Kane tried to avoid a collision with other motorists and crossed both lanes of traffic before riding onto the shoulder of the road. He then continued north on Harpswell Road before losing control and sliding to a stop, police said.

Police said the investigation is not complete and it is not clear whether the brothers were racing.
