Speed was a factor in a head-on collision between two dirt bikes in East Oakland on Monday night that left one 21-year-old man dead and another 21-year-man injured, police said.
Both riders, who are Oakland residents, were ejected from their dirt bikes and neither of them was wearing a helmet, according to police.
The collision was reported in the 3200 block of Courtland Avenue at 9:12 p.m. Monday.
Responding officers determined that one dirt bike was traveling south on Courtland Avenue and another dirt bike was traveling north on Courtland Avenue and both were speeding when they collided head-on, police said.
Paramedics responded and provided medical treatment but one of the riders was pronounced dead at the scene, according to police.
The other rider suffered serious injuries, was transported to a hospital for treatment and is listed in stable condition, police said.
Alcohol was not a factor in the collision, according to police.
The name of the rider who died is being withheld pending notification of his next of kin.
Oakland police said the collision is still under investigation and anyone who has information about it should call their traffic investigation unit at (510) 777-8570.
