Five armed robberies have been carried out at the same north Dublin supermarket since mid-December, including two in the space of only three days.
The Tesco Express at Cardiffsbridge Road, Finglas, has the unenviable distinction of being one of the most raided stores in the country.
This has led gardai to set up a special policing operation and the store to upgrade its security procedures, including closing early.
"Staff have been left traumatised and the community is very concerned," a source told the Herald.
"People just cannot believe that these robberies are happening at such a rate."
While exact details of all the raids are not available, the latest incident happened at around 8.30pm last Monday when two men armed with a hammer and a crowbar entered the store.
They threatened staff before escaping with a sum of money from the till.
They were seen fleeing the scene in a silver-coloured Toyota Yaris.
That robbery happened less than 72 hours after the store was targeted by two men, one armed with a wheel brace and the other with an unknown implement.
At around 9.30pm on February 24, a male security guard who tried to tackle the raiders was hit with the wheel brace as the thugs ordered staff to empty a cash register.
On that occasion the thieves fled on foot. One was wearing a balaclava and the other a white beanie. The security guard was not seriously injured.
Gardai confirmed the store was also targeted at 9.30pm on January 25 when two men entered armed with a steering lock and wheel brace.
They threatened staff and demanded money before escaping in a red Mazda car.
At 9.30pm on December 17, three men, two of them armed with a hatchet and a wrench, escaped with cash.
