ANTIOCH -- A gathering by teenagers at a bonfire disintegrated into an argument among some of them, leading to a chase and two crashes that sent five to the hospital, including one arrested on suspicion of driving under the influence, police said.

The chaos happened Friday night around 10 p.m., after a confrontation and argument among teens who were at the bonfire off Laurel Road in a field between Antioch and Oakley, Antioch police Acting Sgt. Santiago Castillo said. All of the teenagers were 17, Castillo said, and the bonfire was illegal.

As the confrontation escalated, a group of four teens left in one vehicle, while another 17-year-old boy followed them in another one, Castillo said. The boy rammed his vehicle into the back of the one with the four teens, causing it to roll over and hit a tree at Hillcrest and Golden Bear drives. The make and models of the vehicles were not released by police.

All four teens were taken by ambulance to a hospital with minor injuries and later released. The 17-year-old driver who rammed them later was arrested on suspicion of assault with a deadly weapon and is expected to face felony DUI charges when toxicology reports are returned, Castillo said.

Antioch police officers in the area investigating another call saw the driver trying to flee and followed him until the teen lost control going around a curve at Hillcrest and Wild Horse Road, Castillo said. The driver crashed into an unoccupied vehicle in the parking lot of a 7-Eleven.

The 17-year-old was taken to a hospital with minor injuries and was arrested upon his release and taken to Juvenile Hall.
