Federal immigration officials will have a permanent office on New York City’s notorious Rikers Island prison under a directive from the Adams administration, which says the move will help with investigations of transnational gangs and terrorist groups.

The Immigration and Customs Enforcement agency, along with agents from the FBI, Drug Enforcement Administration, Homeland Security Investigations and others, are again allowed to be granted office space on Rikers, which currently locks up nearly 7,000 inmates, mostly pre-trial detainees.
