Now this is strange. I just had a phone call from a mobile number. The woman claimed to be from HMRC and said that I had been involved in tax fraud and that an arrest warrant would be issued in two hours. They said that I owed the government £738 and that they believed this was a willful intend to defraud on my part. They said that it was possible that the organisation I work for had not paid the right amount of tax. I work for the NHS! When I said that I did not believe this and suspected that it was a scam they said that I would be arrested in two hours and hung up! At no point did they ask me for any money. I tried calling the number back but it was not recognised. So that was that about? They knew my name and address. Pretty strange really.
