The Taco Bell executive who was fired after allegedly drunkenly attacking an Uber driver is "extremely remorseful" for the incident that was the subject of a viral video, and now wants to apologize to the driver in person, his lawyer said Wednesday.

An Uber driver involved in a violent confrontation that he captured on a now-viral video is reportedly suing the former Taco Bell executive who is accused of assaulting him.

Edward Caban's lawsuit, which seeks damages in excess of $25,000, came Tuesday, the same day that prosecutors in California filed upgraded criminal charges against his alleged assailant, 32-year-old Benjamin Golden.

Caban, in a civil suit filed in Orange County (California) Superior Court, accuses Golden of "assault, intentional infliction of emotional distress, and negligent infliction of emotional distress," according to a story posted online by KABC TV, Los Angeles.

Golden, who lost his job after allegedly beating Caban during an Uber ride last Friday, was slapped Tuesday with further criminal charges that put him at risk of spending up to a year behind bars and paying a $10,000 fine.
