The phrase used by law authorities around the world refers to how muggers target people leaving banks or a financial institution with significant quantities of money on them.
"The thieves follow the customer with the cash and then attempt to take the cash by using force or else break into the customer’s car if they believe that the money is locked inside," Gardai John Finnerty told the Limerick Leader.
"If you simply must use cash be discreet and aware of your surroundings as you enter and leave the financial institution.
"Always vary your routes and times of cash drops and collections. Keep the cash on your person and don’t leave it in your car," Garda Finnerty added.
Gardai said they had recently been targeting criminal groups involved in this type of crime.
"In one operation, three males were arrested at the end of November 2021 and subsequently charged with multiple offences before the courts," gardi said.
"These males are currently remanded in custody. During the course of that Garda operation, the contents of a number of Bank Accounts were frozen and €110,000 cash was recovered.
Gardai advise that, where possible, funds should be transferred electronically to avoid cash transactions.
However, for people who are engaged in cash banking transactions they urge them to be aware of their surroundings, especially if something seems strange as you enter the bank.
"Conceal your bank deposit bags, coin boxes or envelopes as you enter and leave the bank," gardai said.
"Take your bank bag or envelope with you into your next destination. Don’t hide it in your vehicle.
"And always vary your routes and times for cash drops and collections."
Members of the public who suspect they are being followed are advised to dial 999 or 112 immediately and to make their way to the nearest Garda station.
