Fashion giant Primark has started sealing up its shopping bags with blue “sold” stickers in some stores in a bid to crack down on shoplifting.

Primark’s blue ‘sold’ sticker initiative aims to tackle rising levels of retail antisocial behaviour and crime

Customers carrying bags without the blue stickers can now expect to be stopped at the door by Primark security guards, as first reported by The Sun.

The blue sticker labels have the word “sold” printed in different languages and are being put on bag handles at the checkout.

A worker at a Primark store in southeast London told the newspaper: “The thieves would put anything in which didn’t have a tag and wouldn’t set off an alarm.

“They could blend in with customers because you can only get bags from the checkouts. It was very hard for security guards to spot.”

A Primark spokesperson said: “Antisocial behaviour and retail crime is rising right across the retail industry and we’re working with other retailers and organisations to help tackle this.

“We have a range of security measures in place in our stores and we’re now also trialling some new measures to help prevent stock loss, which includes sealing bags with ‘sold’ stickers once a customer pays for their items at the tills.

“We’ll be keeping an eye on this and monitoring the impact these new measures have, listening to feedback from our colleagues and customers.”

Primark did not confirm which stores will trial the sticker scheme.
