More trouble for "the blood of the city" ... the son of Denver Broncos owner Pat Bowlen was arrested for DUI in California on Sunday, TMZ Sports has learned.
31-year-old John Bowlen was pulled over by the California Highway Patrol in the Paso Robles area around 2 PM -- and during the stop, officers determined he was under the influence of alcohol.
He was hauled to a nearby station where he was booked on 2 counts of misdemeanor DUI. He's set to be released later this morning.
This isn't John's first brush with the law -- the former Broncos marketing employee was arrested for domestic violence in 2015 in an incident in which he was also accused of hijacking the phone of his GF when she called 911.
