Manchester police have arrested a 21-year-old fraudster for sending fraudulent text messages to thousands of people to obtain banking details and defraud them. It is estimated that the fraudster sent more than 25,000 short text messages in one day. The number of people falling victim to the scam remains undisclosed. Police say the operation was quite large and could deliver tens of thousands of messages every day. At least some of the messages were sent through EE, one of the largest mobile network operators in the UK, with over 27 million subscribers.
