Violent Gang Leader Can't Be Deported From Britain.

Joland Giwa.

Joland Giwa had been kept locked up for more than four years after finishing a jail sentence for a string of street robberies in Britain but because officials cannot work out where to send him, he is to stay in Britain indefinitely. 

Both Sierra Leone as well as Nigerian government has refused to accept him, and immigration officials are unable to determine his true nationality neither are they sure he gave the correct name and age when he sought asylum in Britain. 
However, a judge ruled it was unfair to keep Giwa locked up if there was no prospect of him being deported – even though he presents a ‘serious risk of violence’ and there is ‘a very significant risk both of absconding and re-offending’.

Giwa is known as the ‘general’ of a notorious gang known for stabbings, shootings and killings on the streets of Croydon, South London, in 2007 and has been ordered to wear an electronic tag to monitor his movements

Giwa, who is thought to be 24, arrived at Heathrow with his twin brother in 1999 on a flight from Nigeria. He had no parent or guardian and no passport or identity documents. He claimed asylum, telling officials he was a ten-year-old from Sierra Leone whose parents were killed in its civil war. His asylum claim was refused but he was given permission to stay for four years, before being given a permanent right to stay in 2005.
