The first group of immigrants has arrived at a new detention center deep in the Florida Everglades that officials have dubbed “Alligator Alcatraz.”

The facility, at an airport used for training, will have an initial capacity of about 3,000 detainees, DeSantis said. The center was built in eight days and features more than 200 security cameras, 28,000-plus feet (8,500 meters) of barbed wire and 400 security personnel.

Immigrants who are arrested by Florida law enforcement officers under the federal government’s 287(g) program will be taken to the facility, according to an official in President Donald Trump’s administration. The program is led by Immigration and Customs Enforcement and allows police officers to interrogate immigrants in their custody and detain them for potential deportation.

The facility is expected to be expanded in 500 bed increments until it has an estimated 5,000 beds by early July.
