Customs officials seize signal jammers

Customs officials have seized 20 signal jammers used by criminals to disrupt monitored security alarms in the first four months of this year.

The equipment was among a number of criminal items seized so far in 2012, including almost 200 firearms and 37 offensive weapons, ranging from swords to batons.

Signal jammers have increasingly been used by criminals in the past two years to disrupt alarm signals at businesses and houses during robberies and burglaries.
