A commuter injured in the Parsons Green terror attack has been hailed as a "legend" who "epitomises British resolve" after going straight to work following the blast.
Peter Crowley was burned by a "fireball" when an improvised explosive device was detonated on a rush-hour Tube carriage, sparking "pandemonium" as passengers fled.
Twenty-nine people were injured by the explosion and resulting stampede.
Mr Crowley tweeted a picture of his "charred head" after the flames from the blast singed his hair.
But instead of going to hospital for treatment to the burns he continued on his way to his job at a nearby carpet shop.
Interviewed on BBC television while still dressed in a shirt and tie, he said he felt "lucky" to be alive after the device, thought not to have detonated properly, sparked a "fireball" on the carriage followed by "pandemonium".
He added: "I'm shaken up now I’ve heard it was actually a planned explosion."
Viewers immediately praised him for going to work.
One tweeted: “Peter Crowley epitomises British resolve! Someone tried to kill him at Parsons Green explosion but he still went to work!”
Another described him as a "legend", adding: "Proper British stiff upper lip. Enjoy time with your family tonight, you deserve it.”
A third wrote: "Respect to Peter Crowley caught up in today's terror attack in London who despite being injured including hair burnt went to work."
Another said: "That Peter Crowley is a little trooper. Working after being bombed! All Londoners should get their carpets from him to show support."
Twenty-nine people received hospital treatment following Friday morning's attack, according to NHS England.
Police said most of the wounded had suffered "flash burns". None suffered life-threatening injuries.
The homemade bomb contained the same powerful explosive, known as "mother of Satan", used in the 7/7 and Manchester Arena attacks.

An 18-year-old man has been arrested in Dover in connection with the Parsons Green attack.
He was held by Kent Police in the port area under the Terrorism Act on Saturday morning.
