But at least some Alligator Alcatraz detainees have had bond hearings, held at Krome Immigration Court this week, according to their attorneys. Krome's immigration court facilities, which exist on site, are the closest to Alligator Alcatraz. Critics frustrated with the creation and operation of Alligator Alcatraz have filed two lawsuits.

The filing Monday of a motion to intervene in the case initially brought by environmental groups signals a new level of opposition by the tribe, which is also a major political donor in the state.

Several immigrant detainees described high tension and anxiety at the remote, hastily constructed facility over a lack of information, recreation and access to medication.
