SAN DIEGO (CNS) - A skateboarder who held on to a speeding car in Ocean Beach early Friday was critically injured when he let go and rode into the path of an oncoming pickup, police said.

Two men in their late 20s were "hot boarding" in the 4900 block of West Point Loma Boulevard about 2:30 a.m. when the accident happened, according to San Diego police Officer David Stafford.

One of the men let go and landed on the side of the road with minor abrasions, while the other let go and rode into the path of a 1999 Chevy pickup, Stafford said.

The second skateboarder struck the front of the truck and sustained significant head trauma, for which he was taken to a local trauma center in critical condition, according to Stafford.

The driver who apparently was towing the skateboarders continued on, he said.
