John Hines, a former Long Beach fire captain who was convicted of a DUI last year, got another four years tacked onto his sentence for making alcohol in jail.
Hines was ordered to serve the sentence Friday.
The Long Beach Press-Telegram reports that Hines filtered hand sanitizer at the Huntington Beach jail and drank the ethanol it produced.
Police Capt. Russel Reinhart told the newspaper Hines used salt to filter toxins out of the cleaning solution before drinking it.
Hines was convicted last year to driving drunk when he hit a bicyclist and left the man critically injured.
As part of a plea deal, he was allowed to serve probation and a year in jail where he worked as a janitor.
