President Trump has called illegal immigration an “invasion” and what's followed is a huge rise in the arrest and detention of migrants. Some have ended up in ‘Alligator Alcatraz’ - an immigration detention centre that was speedily constructed in June, deep in the Florida swampland. It has become a focal point for debates around immigration. Outside its gates, some take proud selfies with the ‘Alligator Alcatraz’ sign; others protest, following reports of poor conditions inside.

‘Alligator Alcatraz’ is now subject to a number of lawsuits. Immigration attorneys say they haven’t been granted proper access to clients inside; environmentalists claim the detention centre is harming the protected wetlands that surround it. Within the last few days, a judge has that ruled that much of the detention centre must be dismantled and no new migrants taken there. It’s a preliminary ruling - and the case will continue to be litigated. The government immediately filed an appeal.

Josephine Casserly follows immigration lawyer Mich Gonzalez as he attempts to meet his client inside the detention centre. She reports from Florida - America’s new frontline on immigration.
