Commerce Secretary John Bryson was under investigation Monday in connection to two separate accidents in California which involved his car and two other vehicles, police said.

A statement released by the Los Angeles County Sheriff's Department said Bryson was in the driver's seat of a Lexus which rear-ended another car waiting at a railway crossing in the city of San Gabriel on Saturday.

According to the statement, Bryson spoke with the three males in the damaged car and then drove away, hitting their Buick again in the process.

"The three males followed him in their car while calling San Gabriel Police officers via 911 and asking for assistance," the statement said.

Bryson then allegedly drove to the city of Rosemead, where he caused a collision involving a second car, police said.

He was later "found alone and unconscious behind the wheel of his vehicle," the statement said.

The secretary was treated at the scene by Los Angeles County Fire paramedics and transported to a local hospital for medical assistance where he was admitted for "treatment for non life-threatening injuries," the sheriff's department said.

Only minor injuries were reported in the other vehicles involved in the accidents, according to the statement.

"The investigation is in its preliminary stages," the sheriff's department said. "At this point in time, there is no indication that alcohol or drugs played a role in the collisions. All parties were cooperative with law enforcement."
