Ohio prison inmates 'built computers and hid them in ceiling'
A prison work programme has backfired, after two inmates in the US state of Ohio built computers from PCs they were supposed to be dismantling for recycling. The unsupervised inmates later hid the PCs in the ceiling of a training room. Investigators found software, pornography and articles about making drugs and explosives on the machines. The discovery came after IT staff flagged unusual levels of internet activity on a contractor's account.
