Federal immigration officials based in Boston have nabbed two noncitizens accused of child sexual abuse either in their own country or here in New England.

U.S. Immigration and Customs Enforcement’s Enforcement and Removal Operations agents arrested Dominican illegal immigrant Emilio Jose Pena-Casilla in Boston on Dec. 17, but announced the arrest on Friday.

He was charged in Boston municipal court in Dorchester in July with assault to rape, kidnapping, two counts of indecent assault and battery on a person 14 years or older and intimidating a witness/juror/police/court official. He was then indicted on the same charges in Suffolk Superior Court that September.

“Today, another victim in Massachusetts no longer needs to fear their predator,” Patricia Hyde, the acting field office director of ERO Boston, said following the arrest.

“Emilio Jose Pena-Casilla stands accused of some very serious offenses against a Massachusetts resident,” she continued. “We hold a sacred duty to protect the residents of our communities, and we will continue to do so by apprehending and removing egregious noncitizen offenders from our neighborhoods.”

The field office says it lodged a detainer — which is a request by ICE to local law enforcement agencies to hold the defendant so agents can apprehend them — to both the Boston Police Department, the Suffolk Sheriff’s office and the court, but that the court ignored it and released Pena-Casilla with GPS monitoring.

The next arrest was of a Peruvian charged in his own country with raping a child. ERO Boston-based agents arrested him in New Haven, Connecticut, on Dec. 16 and announced the arrest on Friday.

The office is not naming the man “due to ongoing privacy issues concerning this case,” according to a statement, and has blurred his face in a photo it released with the statement.

“ERO Boston, in partnership with local authorities, is charged with keeping our communities safe — and we take that responsibility very seriously,” Hyde said in the statement announcing the arrest. “Connecticut is not, and never will be, a safe haven for fugitives accused of harming children.”
