Bomber's half-sister speaks out
Updated on 16 July 2005
He liked rap music and helped with her homework: but when he was fifteen he converted to Islam and everything changed.
In her first broadcast interview, she tells us how her brother started to isolate himself after his conversion - and was only interested in Islam.
She's now struggling to come to terms with his role in the atrocity. Nineteen-year-old Lindsay - who unlike the other three bombers was born in Jamaica - may have played a key co-ordinating role.
It's believed he carried out the attack on the Piccadilly line between Kings Cross and Russell Square. Twenty six people are known to have died in this- the deadliest blast.
Meanwhile in London, the remains of the number 30 bus are being taken to a secure police compound for further forensic examination. Fourteen died in the bus blast, including one of the bomb suspects, 18-year-old Hasib Hussain.
But Scotland Yard is refusing to call them suicide bombers, saying they have yet to clarify the notion they intended to die as well as let off a bomb.
Evidence to fuel speculation they may have thought - or duped into thinking they would survive include their purchase of return tickets to Luton and that the bombs were not strapped to their bodies.
In Cairo, a post-graduate chemistry student from Leeds University is still being held, at the headquarters of Egypt's National Security Organisation.
Magdy al-Nashar denies all involvement in the bombings, though he's reported to have rented a flat to one of the suspected bombers.
He returned to Egypt a week before the attack, and visited the National Research Centre, which had sponsored his studies in Leeds. He presented his PhD thesis and told a former teacher he was going on holiday.
He had apparently been staying in a flat, with his brother, who told reporters he was very happy - he was even looking for a bride and looking for an apartment to live in.
The Prime Minister focussed on what drives bombers to kill, in a speech in London today. In their eyes, he said, they had had a purpose and the battle now was one for heart and minds against an evil ideology.
Nowhere is a more likely battleground for hearts and minds than the madrassas of Pakistan - religious schools frequently accused of teaching extremist ideology.
One of the suspected bombers - Shahzad Tanweer - made two trips to Pakistan and visited this one outside Lahore and another in the city run by a group allegedly linked to Al-Qaeda, though both deny he was ever there.
Pakistani intelligence also claims Tanweer met the man behind an attack on a church in 2002, the man, a member of a militant group Jaish-e-mohammed with links to Al Qaeda, apparently confirming their meeting from his jail cell.
Two more men suspected of links with the British bombers were arrested in Lahore today - bringing the total held in Pakistan now, to six.
