If a stranger speaks to you, barges into your or even falls down in front of you, they may be a thief trying to steal your belongings, police have warned.

During the Christmas period busy shopping areas act as magnets to pick-pockets, many of who distract shoppers while they steal their belongings.

One typical example is a thief saying that you have dropped a note to get your attention before stealing your wallet or purse.

Det Supt Ellie O’Connor, of Redbridge Police, said: “Thefts of your valuables through pickpocket offending causes you distress and upset.

“The loss is often of photographs and receipts which cannot be replaced.”

If you think you are being distracted call for help of store staff or police at the time. “

She says that you should try and stay aware of what is going on around you at all times and keep wallets in a front inside pocket of your jacket or coat.

Finally, she added, be careful when taking money out of a cash machine, particularly if someone offers to help you.

Never give your PIN to anyone including your bank or the police.
