He grew up in Beeston then his family moved to Dewsbury , about 30 km South of Leeds, where his family was acquainted  with Haroon Rashid Aswat s’ family. He learned in South Leeds High School. This school, 12 years later, was attended also by Hasib Mir Hussain - another London 7/7  bomber.

In 2001 Mohammad Sidique  Khan married with Hasina Patel, from Indian Muslim origin that he met in Leeds Metropolitan University as a student of social work. Their daughter Mariam was born in 04/2004. He attended regularly the Stratford Mosque in Leeds.

Mohammad Sidique  Khan worked in Dewsbury Primary School with the children of immigrant families, who had just arrived in Britain, as "learning mentor” from 2002.  He was known as very devoted to his job and did not talk about religion.  Mohammad Sidique  Khan used to travel to his relatives in Pakistan regularly.

Mohammad Sidique  Khan volunteered also, outside his official job, to work with deprived youth in Leeds in Hamara Youth Access Point (HYAP) - an Islamic charity, partly funded by the UK government (a drop-in center for teens in Leeds). In HYAP Mohammad Sidique  Khan got acquinted with Shehzad Tanweer and Hasib Mir Hussain that later committed with him the London 7/7 attack. Mohammad  Sidique Khan and Shehzad Tanweer were also regular worshippers at the adjoining Tablighi-Jamaat Mosque. It is assumed that he used the meetings in HYAP to recruit them to his own terror cell and to carry on, with him, the attack. 

During the investigation of The Fertilizer 04 Plot in 03/2004 the name of Mohammad Sidique  Khan was mentioned several times but in such a context that did not arise special suspicions in MI5 at that time.

On the morning of 07/07/2005 Mohammad Sidique  Khan, with his three friends, drove a car from Leeds to Luton, 30km north of London, and took the train from Luton to King’s Cross station in London. Mohammad Sidique  Khan detonated his explosives on 09:17 near Edgware Road station.

On 09/01/2005 Al Jajeera Arabian TV network in Qatar broadcasted the martyr videotape of Mohammad Sidique  Khan alongside another tape with Ayman Al Zawahiri, the acting leader of Al Qaeda, leaving the impression that the attack was sponsored by Al Qaeda. It is most likely, according to the background and light, that the footage was taken at the same time and place as Shehzad Tanweers’ martyr videotape that was broadcasted in Al Jajeera later on 06/06/2006.

Summary

* It is unclear what made the moderate Muslim, married with a young daughter, with a job he liked and normal life without any special known problems to a Radical Islamic terrorist and a terror cell ringleader,r who said in his martyr videotape  -   “Your democratically elected governments continuously perpetuate atrocities against my people all over the world”.
