The disclosure was made by the Ministry of Justice and as per their statistics, hundreds of the prisoners were accessing social media platforms without the consent of the authorities. Facebook was quick to react and closed all those Facebook profiles following an investigation by the prison officials. Though inmates are actually not allowed to access the Internet, most of the times, they do it via mobile phones smuggled into the prison. A couple of years back, Colin Gunn — one of the most notorious gangster in the UK was caught using Facebook to threaten his enemies while serving his sentence in a high security prison cell.
