Prison officers in a UK prison gave a convicted hacker access to their computer system.

The bloke man was serving a six-year prison sentence for stealing millions of dollars through online credit card fraud. He hacked into his prison's computer network and  paralysed the network at Ranby Prison, close to Retford, Nottinghamshire, England.

The screws were in need of an internal TV station at the facility, officers decided against hiring a third party to set up the system. In a bid to save a bit of cash they gave the job to Douglas Havard and left him unguarded. He set up a labyrinth of passwords to lock everyone else out of the system. Later he gave the key to another prisoner.

Havard was put in isolated confinement  and officials were left to complain to the local papers. Quite why Havard did all this is anyone's guess. It must get dull in prison.
