THE family of one of the London suicide bombers is insisting he must have been "brainwashed".

Relatives of Mohammed Sidique Khan expressed their "deepest and heartfelt sympathy" to the victims, their friends and family.

Khan, 30, who lived in Thornhill Lees, Dewsbury, has been linked to the Edgware Road blast which killed six other people.

In a statement through West Yorkshire Police, his family urged anyone with information to contact detectives to "expose these terror networks who target and groom our sons to carry out such evils".

The statement went on: "The Khan family would like to sincerely express their deepest and heartfelt sympathies to all the innocent victims and their families and friends affected by this horrific and evil act.

"We are devastated that our son may have been brainwashed into carrying out such an atrocity, since we know him as a kind and caring member of our family."

Khan lived at Lees Holm with his wife Hasina and their young daughter.

The statement added: "We would urge people with the tiniest piece of information to come forward."

Khan had been working as a learning mentor at Hillside Primary School in Beeston, Leeds.
