The fight started around 3:28 p.m. after alleged members of the Pagan’s Motorcycle Club and the Demons of Hell Motorcycle Club — a support group of the Hells Angels — became involved in a confrontation in Lindenhurst off Sunrise Highway, investigators said.

The altercation began when members of the Demons of Hell and one Hells Angels member allegedly interrupted a memorial service for a Pagan’s member at a Lindenhurst bar, the DA said.
