An underworld don, who is languishing in a maximum-security British jail, has been using Facebook to run his drugs and organised crime empire and intimidate his enemies.
Colin Gunn, one of the Britain's most dangerous gangsters, has been able to correspond freely with up to 565 'friends' on the social networking site for the past two months, The Times reported.
Gunn, who is serving a 35-year sentence for conspiracy to murder, is said to be still running his drugs and organised crime cartel from jail.
In one Facebook posting, Gunn, 42, wrote: "I will be home one day and I can't wait to look into certain people's eyes and see the fear of me being there."
In another message he wrote: "It's good to have an outlet to let you know how I am, some of you will be in for a good slagging, some have let me down badly, and will be named and shamed, f****** rats."
Gunn, a 'double-A' category inmate, claims he was allowed to set up a Facebook account by prison governors, as it was his legal right.
Jack Straw, Britain's Justice Secretary, said he will crack down on the misusage of Facebook by prisoners. His department insisted that social networking sites are prohibited in jail and Gunn had not received permission to run an account.
His site, which he appears to have been able to update on a daily basis, was shut down on Friday after the report surfaced.
Gunn's criminal empire in Nottingham was one of the main reasons why it became known as 'Assassination City'.
