A California man captured on a now-viral video attacking an Uber driver has apologized for his behavior.

Thirty-two-year-old Benjamin Golden's attorneys say in a statement Wednesday that their client is extremely remorseful for hitting Uber driver Edward Caban and that it's an isolated incident in his life.

Caban is suing Golden over the attack Friday in Costa Mesa in Orange County. Golden also faces up to a year in jail if convicted of assault and battery charges, and he was fired from his job as a brand manager for Taco Bell, based in Irvine.

A video captured by a dashboard-mounted camera shows a drunken Golden repeatedly hitting Caban, grabbing his hair and slamming his head against a window. The video has more than 2 million views on YouTube.
