A shopkeeper has been left stunned after police told him to change his sign calling shoplifters 'scumbags' because it may be offensive.

Rob Davies, 61, who runs the Run Ragged vintage shop in Wrexham, North Wales, installed the notice to tell shoppers some cabinets were locked against theft.

The hard-working retailer put it up after he caught five thieves red-handed in the last 12 months alone and lost roughly £200 of stock to shoplifting.

He felt the police did little to help when he reported the five thefts and so he gave up doing so, instead taking matters into his own hands to protect his small business.

His handmade note reads: 'Due to scumbags shoplifting, please ask for assistance to open cabinets.'
