#LondonBridge: UK Security Forces ‘Missed’ 18 Glaring Red Flags That Could Have Prevented Attack

Youssef Zaghba’s name was on the The Schengen Information System, a cross-European alert system

The police, MI5 and the UK border force missed at least 18 clear chances to tackle the three London Bridge jihadists raising even more serious questions about their ability to stop violent extremists.

MailOnline can reveal there were several opportunities to stop more than one of the terrorists getting into Britain in the first place – but the authorities failed to intervene.

Mastermind Khuram Butt was deemed a ‘low priority’ despite an aborted attempt to wage holy war in Syria, links to several notorious extremists and an appearance on national TV where he unfurled an ISIS-style flag in public.

Friends and worried parents say they reported him to the anti-terror hotline at least three times for extremist behaviour and trying to radicalise children.

The youngest attacker Youssef Zaghba, 22, was waved through at Stansted Airport in January despite Italian police flagging him as a potential terrorist on a Europe-wide warning system designed to alert passport control.

Terrorists: Khuram Butt, Rachid Redouane and Youssef Zaghba massacred seven people in a rampage which started on London Bridge on Saturday night – but the authorities misses many chances to disrupt them
