He lost conciousness and was taken to hospital where he was pronounced dead. G4S released a statement to the effect of: "a detainee was ill and on the flight and died in hospital".
This is the reality of the murderous borders, people who don't fit into the correct 'citizen' model, who don't have the right papers, who don't 'belong' in the UK are brutally treated and deported with fatal results. Whether or not the deaths occur in the detention centre, on the flight, after deportation, during a dangerous illegal border crossing is irrelevant, the fact is Borders Kill!
Fuck their deportations, solidarity to all migrants and especially the Mubenga family at this time.
