A “selfless” off-duty police officer leapt onto railway tracks to rescue a man who fell after allegedly riding his bike along the platform.
The quick-witted officer has been praised after jumping onto the tracks to help the 43-year-old man at Ladywell station.
Lewisham police officers wrote on Twitter: “Just dealt with an incident at #Ladywell train station where a selfless off duty @metpoliceuk officer jumped onto the tracks to assist a male that had fallen onto them and knocked himself unconscious.”
"Everyone is safe and well and @BTPLondon and @Ldn_Ambulance also attended."
It is believed that the man had been riding a bicycle along the platform and fell onto the tracks after colliding with a passenger.
The off-duty police officer bravely helped the man as British Transport Police (BTP) and the London Ambulance Service rushed to the scene, officials said.
People chimed in to praise the officer on Twitter, with one woman writing: "Well done officer you did a brave deed and save a fellow man."
"Top work," said a man echoing the sentiment.
A spokeswoman for BTP said officers were called to Ladywell station following reports of a person on the tracks at 5.14pm on Tuesday.
"Officers attended alongside colleagues from the Metropolitan Police Service," she said.
The rescued man was arrested on suspicion of endangering safety on the railway.
He was taken into custody and released under investigation.
A London Ambulance Service spokesperson said: "We were called at 5.16pm yesterday to Ladywell Train Station to reports of an incident.
"We sent our Hazardous Area Response Team and an incident response officer to the scene.
"We treated a man at the scene for a head injury, who was taken to hospital by police and our incident response officer."
