Norwich clubbers are being urged to keep a close eye on their belongings after around 20 thefts were reported last weekend.

Officers are investigating the thefts, of mainly mobile phones, from venues in the city centre that were reported at bars and nightclubs in the early hours of February 8 and 9. The majority of the thefts were from handbags.

PC Michael Pearce, investigating officer, said: 'Thieves have been sophisticated in their approach, taking phones out of closed or zipped handbags without the victim realising. Busy nightclubs are ideal hunting grounds for thieves – people are less likely to notice someone tampering with their handbag in a crowded bar or nightclub.

'We are urging clubbers to be vigilant and to make sure they keep their property with them at all times. It is possible that criminals will be on the look-out for people using smart phones, iPhones in particular, so please be mindful of where and when you are using your phone.

'If your phone is stolen then please alert door supervisors immediately – the sooner we are informed the greater chance we have of catching those responsible.'

Anyone with information about the recent thefts are asked to contact PC Pearce at Bethel Street Police Station on 101 or call Crimestoppers anonymously on 0800 555 111.
