Man defeats ankle monitor by removing fake leg
UNITED KINGDOM — Two members of staff at a British private security firm have been sacked after an electronic tag was put on an offender's false leg, the company said today.
Christopher Lowcock, 29, wrapped his prosthetic limb in a bandage and fooled G4S staff who failed to carry out the proper tests when they set up the tag and monitoring equipment at his Rochdale home.
Lowcock could then simply remove his leg - and the tag - whenever he wanted to breach his court-imposed curfew for driving and drug offences, as well as possession of an offensive weapon.
A second G4S officer who went to check the monitoring equipment also failed to carry out the proper test.
Managers became suspicious last month, but when they returned to the address a third time, Lowcock had already been arrested and was back in custody accused of driving while banned and without insurance.
