The news comes less than a week after a federal judge ordered the detention center to wind down operations — with the last detainee needing to be out within 60 days.

Officials say that the crosswalk, a tribute to the 49 victims who died during the 2016 mass shooting, was painted over overnight.

Civil rights attorneys in Miami asked a judge to ensure detainees have confidential access to their lawyers. They also want the judge to identify an immigration court with jurisdiction over the center.

Florida's corrections agency and ICE updated an agreement on handling federal immigration detainees, but they did it more than a month after ‘Alligator Alcatraz’ opened. This update was made public Thursday in court documents.

The order, issued Monday, is part of a civil rights lawsuit claiming detainees' rights are being violated.

Attorneys say that the detainees are being held without any charges and that federal immigration courts have canceled bond hearings.

Kevin Guthrie, head of Florida’s Division of Emergency Management, says the case belongs in the state’s middle district, not Miami-Dade.
