Two days before his crazed knife attack in a busy London shopping street, home-grown jihadi Sudesh Amman had been spotted in Poundland buying small bottles of Irn-Bru, parcel tape, and kitchen foil, which undercover police (correctly) guessed he was going to fashion into a fake suicide belt.
Amman was on probation, having been released just 10 days earlier halfway through a sentence for terrorism offences.
