Golden Boy Promotions CEO Oscar De La Hoya was arrested for DUI in Pasadena, CA Tuesday night ... TMZ Sports has learned.
Law enforcement sources tell us the 43-year-old was pulled over for speeding in a Land Rover around 2 AM and during the stop, officers suspected he was drunk.
Earlier in the evening, Oscar was seen at multiple bars in the area, including Barney's Beanery in Old Town Pasadena where he posed for a pic with a fan.
We're told Oscar bombed a series of field sobriety tests and was arrested for DUI. He was cited and released to his manager.
Oscar has struggled with substance abuse for years -- and has been to rehab for alcohol and drug issues in the past.
De La Hoya first admitted in 2011 that he was an alcoholic and drug user. In September of 2013 he admitted himself to a treatment facility.
The move came on the eve of the biggest fight of the year for his promotion company, Golden Boy Promotions, between Floyd Mayweather Jr. and Canelo Alvarez.
De La Hoya, a former 10-time world champion and 1992 Olympic gold medalist, retired shortly after Manny Pacquiao defeated him in 2008.
Messages seeking comment from his representatives were not immediately returned Wednesday.
