Teenage pop fans reportedly caused thousands of euros of damage to stock in HMV Dundrum last week attempting to see pop band JLS.
The Evening Hearld reports that the damage occurred when over a thousand, mostly female, fans stood on CD stock in the store in order to get a better view of the group who were finalists in last year's 'X Factor'.
HMV's spokesman Genaro Castaldo told the paper: “It's cost us about €4,000 in stock.
"It seems some of the girls involved were very small and to see the band piled the CDs on the floor to stand on them.
“The store was left in a pretty untidy state."
Knowing the popularity of the pop group, HMV had tried to limit the signing to 325 fans who had queued up earlier in the day for wristbands.
But fans without wristband flooded the store as the signing took place at 4pm on Friday.
"We expected a really big crowd and that's why we coordinated with the gardaí and security in Dundrum Shopping Centre," Mr Castaldo added.
"The wristbands system should have worked and allowed all 325 people with wristbands to meet the band.
"Unfortunately the fans without wristbands just wouldn't go away and once they got into the store they became over exuberant, damaging racks and CDs. No one was hurt but we had a hell of a job clearing up.
"It was definitely one of the most popular signing sessions we have ever done in Dublin and allowed us to plan better for the next time," he added.
Four-piece band JLS have already achieved a No 1 hit in Britain with their song Beat Again.
