A thief swiped two credit cards and a mobile phone SIM card from a gym locker and used them to buy £25,000 of luxury watches at Bluewater.

Police have released CCTV images of a man they would like to speak to in connection with the theft at a David Lloyd Health Club in Dartford.

It happened on Thursday, January 13 but the images were only released today.

Officers believe it to be a case of ‘SIM swap fraud’, where a SIM card is stolen to gain access to online accounts including banking applications, making it easier for them to change security settings and credit card PINs.

After contacting his card providers the victim discovered they had been used to buy the watches from stores at Bluewater.

Investigating officer PC James Weston said: "We have carried out a number of enquiries into this offence and are now able to release images of a man who we believe can help us.

"Although he is wearing a face covering, we are hopeful someone may still recognise him from the facial features that are visible, from his facial hair or from his distinctive Under Armour clothing.’

Anyone who recognises the man or who has any other information is urged to call the appeal line on 01474 366149 quoting reference 46/8165/22.
