‘Wanted’ for tax evasion

My wife played back a recorded phone message purporting to be from HMRC. It instructed us to call back regarding a legal issue. I phoned the number and spoke to a man with an American accent who confirmed my name and address. He said he had a warrant for my arrest for tax evasion. I’d apparently withheld £5,000 on my tax returns! I knew it was a scam because I’ve always paid tax through PAYE. I later checked the number online (020 3129 5663) and found scam warnings, then reported it to the police via Action Fraud (0300 123 2040). Steve Rothon
