Managing Director for G4S Monitoring Technologies, David Byrne, said:

“On February 16 we were informed by EMS Capita, which supplies the Ministry of Justice (MoJ) with electronic monitoring services in England and Wales, of a rise in the number of ‘tamper’ alerts from tags we supply.

“We undertook testing of sample straps in February and cross-referenced that with our production audit trail.  We identified a manufacturing defect in approximately one per cent of two specific batches of tag strap clips (fastenings).

“Tamper alerts can occur for a range of reasons, but they may indicate interference with the straps which hold the tag in place.

 “This fault posed no risk to the public and has now been rectified with our supplier and the new clip production process has been tested and independently certified by the Ministry of Justice’s (MoJ) approved test laboratory.

“We will work with the MoJ and EMS Capita to replace the straps currently within the system to ensure that no defective straps remain in circulation.”
