LOS ANGELES - Los Angeles County District Attorney Steve Cooley on April 26 filed drunk driving charges against L.A. City Administrative Officer Miguel Santana, the Los Angeles Times reported. 

Santana, the top budget advisor at City Hall, was arrested March 29 in Covina as he was driving a city-owned car home from a charity event. The event, ironically, was a roast honoring Cooley. 

According to Cooley's office, the 40-year-old Santana had a blood-alcohol level of 0.15 percent. Santana faces one misdemeanor count of driving under the influence of alcohol and one misdemeanor count of driving with a blood-alcohol level above the legal limit of 0.08 percent. 

In the days following his arrest, Santana turned in his city car and took a leave of absence to enter an alcohol treatment center. He returned to work at City Hall on April 15.
