U.S. Border Patrol agents encountered a man around 2 p.m. on Oct. 15 after he crossed the border outside a designated port of entry, according to U.S. Customs and Border Protection. CBP said the encounter happened near Mine Canyon, and also said it followed a crossing of the international border near Dulzura.

The man told agents he was an American citizen but carried no identification. A records check later confirmed his identity and U.S. citizenship.

The records check also revealed an active felony warrant issued by the Los Angeles Police Department in connection with an alleged domestic violence offense. The man was turned over to the San Diego County Sheriff's Office for booking on the warrant.

Federal officials imposed a $5,000 civil penalty for entering the country outside a designated port of entry. Justin De La Torre, chief patrol agent for the U.S. Border Patrol San Diego Sector, said U.S. citizenship does not exempt anyone from the requirement to enter through a designated port of entry.
