Immigrants held in small outdoor cages at 'Alligator Alcatraz' in Florida, investigators find

• The Office of the Inspector General (OIG) found the use of the outdoor cages - about 18sq ft (1.67sq m) - was "unprecedented among detention facilities" and dangerous.
• Investigators concluded the centre also did not comply with a number of standards for hygiene, medical care, food, health and safety.
• The Department of Homeland Security’s independent inspector general determined that Alligator Alcatraz failed to comply with at least six different detention standards, including basic medical care, food, hygiene and environmental health and safety.
