A MASSIVE hunt was under way today for the terror mastermind who recruited West Yorkshire suicide bombers to attack London.
Police believe the men who travelled by car and train from Dewsbury and Leeds to take slaughter to the capital last week were probably working to order.
And as police stepped up their nationwide hunt there was a major security scare in Huddersfield.
The university campus on Queensgate was sealed off and hundreds of people evacuated.
It was believed to be a false alarm after a case was found in the university.
Army bomb disposal were called in as police sealed off the campus as staff arrived for work.
Detectives confirmed last night that three of the four London bombers were from West Yorkshire - and had become the UK's first suicide bombers.
One was from Thornhill Lees and the others from Leeds. They killed at least 57 people and left 700 maimed on Tube trains and a bus.
