Burglars use homemade devices to jam house alarms
Gardai have uncovered high- tech equipment used by burglars to disable alarms in homes they are targeting
It is suspected that the device pictured is an alarm "jammer" or "disrupter", which is used by criminals to stop an alarm system sending a signal back to its operating company or gardai.
The device is based on a powerful magnet and has a power cable that needs to be used to keep it charged.
It shows that burglars have upped their game as technology has advanced.
"Before you would have just had to cut the telephone wires, but a lot of alarms are wireless now," a garda spokesman said.
Gardai found the device following the arrest of two men in north Dublin city over the weekend.
The men, aged 28 and 30, were being detained at Store Street Garda station.
A search was later carried out at addresses in Dublin 6 and 8.
It was during these searches that gardai uncovered the alarm jammer and a "number of sophisticated articles" that could be used to carry out burglaries.
Operation Thor is a Garda operation to tackle burglaries which was launched in November,
Some €5m has been given over in funds by the Department of Justice to administer the operation.
A number of arrests have been made under the operation and programmes are also being trialled to try and reduce re-offending rates of prolific criminals.
In one Operation Thor incident an ATM was found when a van was searched in Monaghan.
