    The fourth bomber was Jamaican-born Germaine Lindsay who lived in Buckinghamshire

    CCTV stills and a picture of Hasib Hussain were released by police

  • Officials in Pakistan have supplied documentation showing that Khan and Tanweer visited Pakistan during 2004

  • Police are now hunting those who supported, financed, encouraged and armed them

  • A suspected al-Qaeda member entered the UK via a Channel port two weeks before the bombings, but was not put under surveillance. He flew out a couple of hours before the bombs went off

  • Explosives found in a house in Leeds are said to be similar to those used in al-Qaeda attacks and made from ingredients available in high-street chemists

  • Met Police Commissioner Sir Ian Blair said he expected the investigation to uncover a "clear al-Qaeda link"


  • The four men were captured on CCTV at King's Cross station, wearing rucksacks, shortly before 0830 BST on the morning of the attacks

  • The men had travelled to King's Cross on a Thameslink train from Luton. CCTV footage of them in Luton has also been released in an attempt to find out more about what they were doing

  • At King's Cross, they split up, three of them detonating their bombs on separate trains simultaneously at 0850 BST

  • Hussain's bomb went off 57 minutes later, at Tavistock Square.

  • The blasts killed a total of 56 people, including the bombers

    The blast at Kings Cross killed 27 people, 14 died on the bombed bus at Tavistock Square, the attack at Edgware Rd killed seven and the Aldgate blast killed eight.

  • Police sources have told the BBC they have not recovered any timing devices from the bomb scenes, possibly indicating that detonation was by hand

  • Hussain had been reported missing by his family, and personal belongings of some of the group were found at the bomb scenes

  • Counter-terrorism officials believe the group of four would have had an outside "controlling hand" who could still be at large

  • More than 3,500 calls have been made by the public to an anti-terrorist hotline and police have taken more than 800 witness statements.

  • Police are also analysing more than 6,000 CCTV tapes
