The lives of the four men believed to be the bombers involved in last Thursday's terror attacks in London have started to emerge.

The names of three of the men have already been revealed and police say they now know the identity of the fourth man — also from the Leeds area of Yorkshire.

SHEHZAD TANWEER: Born on Dec. 15, 1982, at St. Luke's Maternity Hospital in Bradford, Tanweer lived all his life in the Beeston area of Leeds. His father, Mohammed Mumtaz Tanweer, was born in Pakistan and owns a fish and chip shop near their home on Colwyn Road.

Neighbors described Tanweer as a "good Muslim" who lived with his parents, his younger brother and two sisters in their semi-detached white pebbledash house.

He reportedly attended Wortley High School before moving on to Leeds Metropolitan University. The sports science graduate was said to have loved cricket. His friend Mohammed Answar, 19, said they played the sport together only last week.

"It's not in his nature to do something like this, he's is the type of guy who would condemn things like that," said Answar.

Tanweer had reportedly traveled to Afghanistan and Pakistan within the last six months, prompting fears he may have attended an Al Qaeda training camp. Sources said there was "strong" forensic evidence linking him to the blast on the Underground train near Aldgate.

HASIB MIR HUSSAIN: It was the disappearance of Hussain on the day of the attacks that provided one of the vital clues, which led police to Leeds. The 19-year-old was reported missing by his mother at 10.20 p.m. on Thursday after failing to return home from London.

He had told his parents that he was going to the capital on the day of the bombings with friends.

Hussain lived with his parents in the Leeds suburb of Holbeck, where a three storey red-bricked terrace house in Colenso Mount was searched. One neighbor said the family had lived in the house for more than 20 years.

The man, who asked not to be named, said: "The lad was born here. He lived here all his life. They were very, very nice people. We all knew them but I wouldn't say I knew them well. They were just a very nice family."

Hussain reportedly attended Matthew Murray High School and apparently became very religious two years ago. His driving license and cash cards were found in the mangled wreckage of the No. 30 bus, which blew up in Tavistock Square and caused 13 deaths.

MOHAMMED SADIQUE KHAN: The third man to be named as a suspect came from Dewsbury in West Yorkshire. Of Pakistani origin, the father-of-one was married to Hasina and their baby girl is thought to be about eight months old.

Khan, 30, originally lived in Beeston but moved to Lees Holm in Dewsbury about five months ago.

Neighbors said he worked with disabled children while his wife was involved in education. His mother-in-law, Farida Patel, lives with her son Arshad nearby, in a house, which was also believed to have been raided by police.

Neighbour Sara Aziz, 28, said: "I noticed police outside and saw the lady who lived there come out with a baby. They seemed a right quiet couple. He goes to the gym. The reason I say that is because I've seen him carrying a bag over his shoulders some mornings. I saw him last week."

Documents belonging to Khan were found in the debris of the Edgware Road blast.
