British Transport Police officers investigating threats made on board a train at London Bridge are appealing for further information.
The incident happened at around 8.28pm on Friday, April, 12.
An intoxicated man is reported to have boarded the rear of a Beckenham-bound train at London Bridge.
He was with a woman and was waving a Union flag.
He began acting aggressively to passengers on the train and made references to Bloody Sunday – the infamous episode in 1972 when British soldiers fired shots at protesting unarmed civilians in Derry during The Troubles in Northern Ireland.
He is then reported to have threatened a passenger after being challenged.
The man, a 29-year-old from Beckenham, was arrested on suspicion of nuisance behaviour. He was released while officers carry out further enquiries.
Officers would like to speak to anyone who witnessed the incident, especially a passenger who is reported to have filmed the incident on their phone.
Witnesses can contact BTP by texting 61016 or by calling 0800 40 50 40 and quoting reference 623 of 12/04/19.
Alternatively, you can call Crimestoppers anonymously on 0800 555 111.
