Newark Mayor Ras Baraka says immigration detainees are now being held at Delaney Hall.

Baraka spoke Monday from City Hall. He says it's happening even though the city and courts have not given approval for the detainments. The mayor says he is now having city attorneys file an injunction to stop it.

“We don’t know what’s going on in there, we don’t know how many people they have in there. We don’t know if there are code violations in there," Baraka said.

The mayor discussed the GEO Group, which runs the facility as part of a $60 million contract with ICE.

“They’re following the pattern of the president of the United States, who believes that he can do what he wants to do and obscure the laws," he says.

As a sanctuary city, Newark officials have been in the courts in recent weeks trying to block Delaney Hall from opening.

City officials have been trying to protect immigrant families, who the mayor says worry they’ll be arrested by ICE and sent to Delaney Hall.

Baraka said that fire inspectors were blocked on Monday from getting inside Delaney Hall to perform inspections. Health inspectors also haven’t been allowed inside to check on the kitchen and laundry room.

The city says the inspections need to take place before a certificate of occupancy is issued.

The GEO Group said in a statement that it does have a certificate of occupancy, which dates back to 2007.

“Another unfortunate example of a politicized campaign by sanctuary city and open borders politicians in New Jersey to interfere with the federal government’s efforts to arrest, detain, and deport dangerous criminal illegal aliens," said a spokesperson for the GEO Group.

Delaney Hall has been the site of regular protests following the uptick in arrests by ICE, and as plans were announced to reopen the facility.

A judge will need to rule on the city’s request for an injunction.
