No crash charges for ex-Commerce Secretary John Bryson

John Bryson was not accompanied by security at the time of the crashes as he was on 'personal time'

A former US cabinet minister investigated over a hit-and-run over three crashes in California will not face charges, prosecutors have said.

John Bryson, 68, said he had suffered a seizure and resigned from his post as commerce secretary on 21 June, days after being found slumped at the wheel of his car.

The ex-utilities boss said his health issues could distract him from his job.

At the time, police said drugs or alcohol were not involved.

Investigating the incidents, they said that on 9 June Mr Bryson hit a car that had stopped for a train in San Gabriel, near Los Angeles.

He got out of the car and spoke to the passengers, but hit the car for a second time as he was driving away.

He hit another car a few minutes later, before he was found unconscious and alone at the wheel.

Before he was appointed as Secretary of Commerce, Mr Bryson was the head of Edison International, a US utilities company, and has served on the boards of Boeing and Disney.
