A group carrying kit bags and wearing Imperial College Rugby sweatshirts stripped bare and ran amok on the District Line train yesterday evening, according to commuters.
They boarded towards the front of the 17.19 Richmond to Upminster service, swigging from bottles of wine, a witness said.
At least one of them was said to have stripped naked on the platform at Richmond station and boarded the train.
They were apparently playing a game in which you had to get off the train, strip, and board again before it moved off.
