In a shocker, nearly 350 criminals in British jails have been found using Facebook with some of them taunting victims and threatening to seek revenge.
All the profiles were closed by Facebook following investigations by prison officials.
In the past two years, nearly 350 people have been caught posting entries on Facebook while serving a sentence; UK Ministry of Justice figures show.
Violent criminals have been using Facebook to taunt victims and their families from jail, it was disclosed yesterday, the Daily Telegraph reported.
It is likely that hundreds more have successfully used the site without authorities being made aware. Inmates are banned from using the internet but access the web through mobile phones smuggled into jails.
Two years ago it emerged that Colin Gunn, one of Britain's most dangerous gangsters was using Facebook to threaten his enemies from a high security prison cell.
"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. It's good to have an outlet to let you know how I am, some of you will be in for a good slagging and some have let me down badly and will be named and shamed....," Gunn had posted. The 44-year-old was jailed in 2006 for the revenge killings of John and Joan Stirland.
Recently a teenager who killed a shopkeeper posted a series of pictures on Facebook showing him making gangster salutes.
"If something is happening which violates our use policy we will be very active and robust in removing it," a Facebook spokesman said.
