49 offenders remove monitoring devices to jump bail

The agency would in December evaluate the use of EM devices, which began on March 1 in Thailand, Punnapat said. The use of EM devices is also required by the Criminal Procedure Code to be evaluated after three years of use.
Punnaput oversees the control centre for offenders on temporary release and wearing EM devices. He said 1,884 EM devices – of the 5,000 so far distributed to 163 courthouses nationwide – were put to use and had been monitored in real-time by officials of the control centres around the clock.
Within two minutes of a wearer’s signal being lost from the monitoring screen, the centre would call the wearer, he said. The official would query the wearer about the lost signal, said Punnaput.
If the signal remains down for more than one hour, an assumption is made that the wearer could be attempting to flee and an arrest warrant is sought. 
An offender found to be deliberately tampering with an EM device to jump bail would see his guarantor fined and would be brought to detention without enjoying another opportunity to seek, he added.
As of July 31, there had been 49 cases of lost EM signals, with 18 fugitives recaptured after arrests warrants were issued.
