A man from north London accused of being an Islamic extremist has had his British citizenship revoked.
Family and friends of Mahdi Hashi, 23, from Camden, claim the government acted because he had refused to become an informant for the security services.
Mr Hashi, from Camden, is currently thought to be in a jail in East Africa.
Revoking his nationality in the summer, the Home Office said he was considered a threat to UK national security due to his "extremist" activities.
The government has since made no further comment.
Mr Hashi was born in Somalia and moved to London with his family at the age of five.
In 2009, Mr Hashi claimed he and a group of friends - all of Somali origin - were approached by MI5.
'Posing as postmen'
One of them, Mohamed Nur, said: "One day they (MI5 officers) came to my house pretending to be postmen. When I let them in they accused me of being an extremist.
"They said the only way to remove that taint from my name is if you work for us, otherwise wherever you go we can't protect you... We perceived it as blackmail."
Another friend, Abshir Ahmed, said: "I felt bullied. I don't want to work with MI5 so they should just leave me alone."
