We'll also be looking at criminal credit card fraudsters who can steal your bank details just by using their mobile phones!

Case 1: Pensioner assault

94 year old Emma Winnall was assaulted as she slept at her home in Moseley, Birmingham, some time between 9pm on April 30th and 9am the next morning, when she was found by her daughter, Joyce. Detectives believe that Mrs Winall who is wheelchair bound, deaf and almost blind was the victim of mistaken identity.

Her family believes a drugs gang burst into her home thinking she was a relative of a rival dealer. Mrs Winnall underwent emergency surgery after suffering a fractured skull, broken arm and wrist and a partially severed finger, which her family believes was hacked off as a warning. Mrs Winnall has now woken up after being sedated since the attack last week.

Case 3: Hackney play centre

A play centre that counts David Cameron, Liz Hurley and Elton John among its patrons has been targeted by burglars eight times since last August. The Kids Adventure Playground in Spring Lane, Hackney, where most of the children are disabled or have learning difficulties, has been repeatedly ransacked by intruders.

Parents of the nearly 200 children who use the centre said today they were sickened by the attacks. The children see the police coming in all the time and it makes them feel anxious. They have stolen the centre’s lawn mowers, petty cash and specialist equipment as well as damaging their CCTV cameras, which the it cannot afford to replace.

Card scamming with Thomas Cannon

Contactless cards are available to Natwest, Barclays, HSBC, RBS and Lloyds customers. Just by touching their card on the reader at various high street stores, they are able to pay for goods which are under £10, without using chip and pin or signing for purchases.

Instead of storing data on a magnetic strip, the contactless payment card stores data on a microchip embedded in the card's plastic, which is fitted with a radio antenna capable of transmitting the data to a card reader without physical contact.

They are currently used by around 20 million people, they have been introduced to be quicker and more convenient than cash or traditional card payments.

However, fraudsters can purchase these handheld receptors for as little as £7 on sites like eBay, and simply by walking past cardholders can access their bank details.

Thomas's top tips

  • Check your bankcard statement every month for fraudulent transactions
  • Use a shield - either put tin foil round your cards or purchase a wallet with a shielding sleeve
  • Credit card sleeves, £2.50 and Leather credit card holders, £7.99 from rfidprotect.co.uk
