At 14:14 BST I got a call on my mobile from +49 168 61275759 claiming to be from ‘National crime squad’ (or similar) saying that my number had been implicated in serious crime so my national insurance number was going to cut off urgently unless I pressed 1. The voice was male, posh English, with a note of urgency.
I did not press 1. I have since blocked the number.
