A U.S. Customs and Border Protection agent is facing charges after a state trooper arrested him for driving while intoxicated in Saint Paul.

The federal agent was allegedly found slumped over the wheel of his vehicle and covered in vomit early Tuesday morning.

Alfredo Mancillas Jr., 31, of Corpus Christi, Tex. is charged with one count of third-degree DWI for refusing to submit to a breath test and one count of fourth-degree DWI for operating a motor vehicle under the influence of alcohol.
