Today the country reflects on the anniversary of the 7/7 bombings where Sutton Police were among the first emergency services to respond following the deadliest terrorist attack on UK soil.
10 years ago Sutton Police helped victims and survivors after four bombs exploded in central London killing 52 innocent people, and injuring around 700.
The four bombers also died during the attacks.
In the early hours of the morning of July 7, 2005, West Yorkshire-based bombers Mohammad Sidique Khan, 30, Shehzad Tanweer, 22, and Germaine Lindsay, 19, left Leeds in a rented car and drove south to Luton where they picked up the fourth, and youngest, member of the group, Hasib Hussain, 18, before they continued via train to King's Cross.
Khan, Tanweer and Lindsay then entered King's Cross station around 8.38am, hugged each other and went their separate ways boarding trains on the Central and Picadilly lines.
The three detonated their explosives just minutes after they had separated at around 8.50am on the underground at Aldgate, Edgwar Road and Russell Square.
Hussain, the youngest of the four at 18, later blew himself up on a the upper deck of the number 30 bus in Tavistock Square around 9.47am.
The superintendent at the time, Warren Shadbolt, who is still with Sutton Police, praised the officers who he said endured the most "appalling" conditions as they attended to the survivors.

Inspector Warren Shadbolt was with Sutton Police at the time of the 7/7 attacks
In July, 2005, he said: "They performed fantastically well in appalling conditions - conditions that many of us thankfully will never have to face.
"They escorted people from the train, they freed them from areas where they were trapped, they provided first aid to very badly injured people and they provided comfort to others on the scene.
"You think it- they did it- they undeniably saved lives."
He added: "We're all very proud of what they did - but that's not to take away the pain of the appalling, cruel and terrifying act that occurred."
The Mayor of Sutton, Councillor Muhammad Sadiq, will be attending a memorial service marking the 10th anniversary of the bombings at St Paul's Cathedral at 11am today.
Families of the victims and survivors will also be in attendance, alongside HRH The Duke of York, Mayor of London Boris Johnson and members of London's emergency services.
Sutton Council is holding a minute's silence starting at 11.30am this morning.
