A vigilante has been interviewed by police after taking the law into his own hands when a London Underground passenger exposed himself in front of children.
British Transport Police said the man was quizzed on Monday and their investigation into the incident is ongoing. The naked male has now been sectioned.
Footage posted online shows as suspect dropping his trousers on a Hammersmith and City line train at around 3.30pm on Thursday.
When challenged by commuters on the eastbound service at Upton Park station, a fight erupts.
Up to four men stepped in when he repeatedly refused to pull up his pants and began shouting repeatedly “f*** off”.
Police believe the naked male, who has since been detained under the Mental Health Act, was assaulted by them.
Detectives appealed for witnesses to the incident but there have been no arrests over the brawl.
A spokeswoman said: “Officers were called to reports of a man exposing himself on the District line at East Ham Underground station at around 3.30pm on August 7.
“The man had been assaulted by a number of other passengers and was initially arrested by an off-duty officer, before being detained under the mental health act and taken to hospital where he remains having been sectioned.
“One man involved in the assault has been interviewed by officers, and the investigation into the incident is ongoing.”
When the suspect swears, one commuter can be heard replying: “What do you mean f*** off? You need to get off the f***ing train. Now. There are kids on here.”
The naked man continued to shout and wave his belt before more passengers stepped in to restrain him.
A fight then appeared to break out, with the group punching and kicking him to the floor of the carriage.
He was seen with his hands forced behind his back before being unceremoniously thrown off the train by several men.
A photograph later showed him pinned to the ground on the platform at East Ham station, where passengers waited with him for help to arrive.
Anyone who witnessed what happened and hasn’t already spoken to police, is asked to contact BTP by texting 61016, quoting ref 458 of 07/08/25.
