Authorities say an off-duty U.S. Border Patrol agent was injured when the government vehicle he was driving was rear-ended by a suspected drunken driver.
The Arizona Department of Transportation says Diego Garcia was speeding along Interstate 19 north of Nogales on early Friday when he slammed into the agent's car.
Garcia's car then hit the guardrail and concrete barrier on the east of the road before heading into the median.
Garcia was taken into custody on suspicion of driving under the influence.
Border Patrol officials say the agent was driving home from work when the crash happened. He was treated for non-life threatening injuries and released from the hospital.
