These images show the bravery of a selfless commuter who leapt to the aid of a man who had fallen onto live London Underground tracks.
Just before 5pm on Tuesday a 47-year-old man was standing on a northbound Northern Line platform at Tottenham Court Road underground station, where he suddenly became unwell.
Stumbling on the platform, he fell onto the live tracks.
As shocked bystanders looked on, a backpack-wearing commuter jumped onto the tracks and hauled the man to safety.
Meanwhile his fellow travelers notified station controllers in an attempt to slow down the approaching train.
The man was treated by paramedics at the scene before being taken to hospital. He received light cuts and bruises but will make a full recovery.
Praising the work of the mystery hero, Superintendent Chris Horton, said: “Going onto the tracks is extremely dangerous but the bravery of this man has to be praised.
“The man sprung to the rescue and hauled him back onto the platform, whilst other commuters alerted the emergency services.
“Whilst the approaching train was immediately put on a red signal, the quick thinking of him and other passengers on the platform avoided what could have been a tragedy.
“On behalf of everyone at British Transport Police, I’d like to commend this man for his brave actions – his quick thinking most likely saved the man’s life.”
Meanwhile, people on social media have also been praising the mystery hero’s actions.
Claire Roberts tweeted: “There are some incredible people walking this earth, very brave to take action like he did. He has my greatest respect.”
“Wow! Brave soul. Respect,” added Karen Whitehouse.
