PEOPLE are warned to be cautious when dealing with unknown callers after a young couple received several telephone calls claiming there was a problem with their computer.

The incident happened in Grundisburgh, near Woodbridge, on Friday.

A 25-year-old man received a call on his landline from a man who claimed there were problems with the computer.

The would-be victim realised something was amiss because he was already online and there were no problems. During the conversation several pop ups came up – including one requesting his bank details - and the 25-year-old ended the call. The next day several screens came up saying there were viruses on the computer.

On Tuesday the 25-year-old’s partner received a call from a man again saying the computer had problems that had to be dealt with urgently. She was told she had to buy a key and should give out her bank details. When challenged the man became abusive so she hung up. Other calls followed from different men who were abusive.

Suffolk police are urging people receiving such calls never to give out personal details.

A spokeswoman said: “Please be extremely careful when dealing with any unknown callers, whether they are on your doorstep or on the phone, and think before responding to unsolicited calls or emails.

“If anyone attempts to get your bank details in circumstances such as these - hang up.

“If you suspect there may be a real problem with your computer seek help through a genuine local business or your original supplier.”
