A New Mexico judge has resigned after a man with alleged ties to the Tren de Aragua gang was arrested at his residence.

Magistrate Judge Joel Cano, of the state's Doña Ana County, submitted his resignation letter March 3, without providing an explanation.

Cano has been in the position since 2011, according to the Albuquerque Journal newspaper.

“Working with each of you has been a very rewarding experience for which I will remain eternally grateful,” his letter reads, according to the newspaper. 

The person arrested has been identified as Cristhian Ortega-Lopez, a 23-year-old illegal immigrant.

Federal law enforcement has accused him of being connected to the Venezuelan gang. 

Court documents show Ortega-Lopez lived in El Paso, Texas, before he met Cano's wife, Nancy Cano, while doing construction work. He accepted her offer to stay at a guest house behind the family residence.

He was at the residence when Homeland Security Investigations, under U.S. Immigrations and Customs Enforcement, executed a search warrant on Feb. 28 for his arrest.

Ortega-Lopez is now in custody without bond at the Doña Ana County Detention Center and is facing federal firearm charges.

Neither Cano nor his wife have publicly commented on the matter.
