British Transport Police said they are trying to identify several passengers who restrained and allegedly assaulted a naked man on a London Underground train last Thursday. The incident unfolded at about 3:30 p.m. on a District line service between Upton Park and East Ham after the man dropped his trousers, exposed himself in front of children and swung a belt at fellow riders. According to a BTP statement, up to four passengers tackled the suspect, pinned him to the floor of the carriage and carried him onto the platform at East Ham, where an off-duty officer arrested him. The man was later detained under the Mental Health Act and taken to hospital. Detectives are examining video footage and have appealed for witnesses to determine whether the force used by the passengers constituted an assault. No arrests have been made in relation to the confrontation. The case has reignited debate over public safety on the capital’s transport network and the legal risks faced by commuters who intervene during violent or sexual incidents.
