Border agents in Nogales arrested a man this weekend after they say he tried to cross into Mexico with $420,000 in undeclared cash.

Victor Dariel Peralta-Cohen, 33, of Mexico, was driving through the Dennis DeConcini border crossing Saturday when agents pulled him over to inspect his car, the agency said in a news release Monday.

Agents found the cash hidden under the vehicle’s rear seats and in the trunk.

Peralta was referred to U.S. Immigration and Customs Enforcement’s Homeland Security Investigations.
