Inmates in the biggest jail in Britain are ordering drugs, continuing to run criminal activities and plotting escapes using mobile phones that are smuggled into the building, according to a watchdog report.

The “apparently limitless” supply of mobile phones in Wandsworth prison is increasing the supply of drugs on the wings as well as “fuelling a whole group of new users”, the report said. Almost 250 mobile phones were found inside Wandsworth, in southwest London, in the first five months of this year, the report from the prison’s Independent Monitoring Board disclosed.

The report said that it was only a matter of time before a “very serious incident” took place because of mobile phone use. timesonline.co.uk
