A warning has been issued to motorists after thieves used signal blockers to steal from cars in Co Westmeath yesterday.

Gardaí in the midlands are advising motorists to double check that their cars are locked after the two thefts in the Golden Island area of Athlone.

The signal blockers are used by thieves to prevent someone locking their car by remote control.

The blocker, which is usually operated by someone near the vehicle, prevents the car from locking, and if the owner does not notice, the thieves can simply open the car door when the driver is gone.

It is understood both of the victims of yesterday's thefts had taken money out of the bank before they were targeted.

Gardaí are advising motorists to check their car door handles after locking in order to ensure the car is secure.
