What we know so far about the Beckenham train stabbing

A teenager has been arrested after a man was stabbed and left with life-threatening injuries while on a train in south London.

Reports of two men fighting while entering the train saw officers from British Transport Police (BTP) rush to Beckenham Junction station alongside colleagues from the Metropolitan Police and London Ambulance Service on Wednesday afternoon.

Shocking footage of the incident was shared on social media, showing a man holding a large blade attacking someone on the floor.

What we know

BTP have confirmed to Yahoo News UK that a 19-year-old man has been arrested on suspicion of attempted murder. A knife has also been recovered as part of the investigation. The victim, a man in his 20s, was taken to hospital and is in a critical but stable condition.

The incident took place after two men boarded a train at Shortlands railway station in Bromley just before 4pm on Wednesday. In the footage, a man is seen holding a large blade, and seemingly lunging at a man on the floor with the knife.

Onlookers can be heard calling the police to alert them of what was happening and where they were. Some passengers stayed in their seats, while others could be heard screaming and running to the other end of the carriage. The footage also shows that the incident took place in daylight, shortly before the evening rush hour.

Train services in the area were disrupted until around 6.30pm as police dealt with the incident. A Southeastern trains spokesperson said they were assisting BTP with their investigation and providing CCTV footage to officers.

BTP’s Assistant Chief Constable Allan Gregory described the stabbing as “incredibly concerning” and said there would be an “enhanced police presence at stations in the area” on Thursday morning. He reassured passengers that there is no risk to the wider public.

Superintendent Darren Malpas said: “We understand the concerns of the public following this incident and our detectives have been working tirelessly to investigate. I hope this arrest will bring some reassurance to those on the rail network.

“High-visibility patrols will continue in the area and across the network as a visible reassurance to the travelling public.

What we don’t know

While a man has been arrested, we do not yet know his identity. The victim has also not been identified.

The footage of the incident shows the middle of the attack, with no context about how or why it started and whether the two men knew each other.

Some people in the area wrote about witnessing the aftermath of the attack on Facebook. One person said they saw a member of the public with two planks of wood “going after whoever has the knife”, but these reports could not be verified.
