Knife attacker spotted as police launch major manhunt after passengers witness stabbing on Bromley train

A major police manhunt is underway after shocked passengers witnessed a stabbing on a train in south London, which left a man fighting for his life.

Police received reports of an altercation between two men who boarded the train at Shortlands in Bromley just before 4pm on Wednesday.

Video filmed by a passenger shows one of the men brandishing a large zombie-style knife lunge at the other man on the floor of the carriage while terrified passengers plead with him to stop.

The clip published on social media has been viewed almost 18 million times. A second clip showed a air ambulance land near Beckenham station where the train stopped.

Police have launched an urgent hunt for the attacker, described as a black man who was wearing a black hooded jacket, black trousers, and wearing a face mask.

A statement issued by British Transport Police said: "Officers are carrying out extensive enquiries to trace the suspect for a stabbing at Beckenham Junction.

"You will see an enhanced police presence across stations in the area throughout the night and into tomorrow. We do not believe there is any risk to the wider public."

A Southeastern trains spokesperson said: “We are aware of a serious incident on board one of our services this afternoon. We are urgently assisting the British Transport Police and would urge anyone with any information to contact them immediately.

“All of our trains are fitted with CCTV and we will be providing this footage to the British Transport Police to assist with their enquiries.

“We also have an integrated safeguarding team, comprised of Southeastern, BTP and Network Rail colleagues and we are already working together to find those responsible.”
