A charity shop owner has revealed he is verbally abused by customers 'at least twice a week'.

Tone Jarvis-Mack, founder of The Fertility Foundation, says aggressive behaviour and shoplifting is 'out of control' across Britain's retail sector.

And the 54-year-old believes charity shops are specifically targeted by criminals due to the belief 'we get stuff for free', even though every theft deprives good causes of crucial funds.

Other charity shop owners have complained of a 'significant increase' in thefts and anti-social behaviour, while overall retail crime is surging - with a 20 per cent annual increase in shoplifting offences.

Mr Jarvis-Mack has now decided to install a facial recognition system called Facewatch at his shop in Waltham Cross, Herts, in a bid to protect staff against thieves and customers who turn violent over minor issues, such as refund disputes.
