A car show Sunday at Bald Hill erupted into a violent brawl between rival motorcycle clubs, according to police.

Suffolk police say between 60 and 70 members of the groups were involved in the fight. Cellphone video taken by a witness allegedly shows members of the Hell's Angels and the Pagans squaring off just after noon.

One witness says the motorcyclists were beating each other with tools, including wrenches and hammers.

Witnesses say the massive fight took place just steps away from where parents and children were trying to enjoy the show. There were children in Halloween costumes attending the event.

Police say two people were injured, but neither wanted to press charges. No arrests were made.

After the bikers dispersed, patches of blood-soaked concrete and Hell's Angels fliers were seen scattered across the parking lot.
