I believe this to be a scam call supposed from HMRC (Scam call)
This is a scam call from scammer claiming to be HMRC, Press 1 as being investigated for tax fraud if you do not press 1 you will be arrested. HMRC would not threaten like this and I have reported the number to HMRC who are dealing with. I have blocked the number on my mobile.
Told me Inland Revenue had an arrest warrant out for me.
Do not reply it is False
Just Block the Number if in doubt look on line for Inland Revenue and call them direct from a different number.
