The U.S. attorney in Connecticut says a man has pleaded guilty to facilitating heroin trafficking and illegally entering the U.S.

The office said Monday Mexican citizen Onel Arana-Gervacio, 44, pleaded guilty in Hartford to conspiracy to distribute heroin and illegal re-entry.

According to U.S. Immigration and Customs Enforcement, Arana-Gervacio is one of five people charged with participating in a trafficking ring in Alabama, Connecticut and Rhode Island.

Prosecutors say Alabama police stopped a car hauler carrying a vehicle registered to Arana-Gervacio back in 2016 and found a hidden compartment commonly used for contraband.

The car was tracked to Connecticut and Rhode Island.

Authorities say in January 2017, they seized $260,000 from the car and heroin, cocaine and drug distribution materials from the Hartford residence where it was parked.

Arana-Gervacio was removed from the U.S. in 2013.
