Two girls shut down the Docklands Light Railway for over an hour. They climbed on top of the train at Canning Town Station at 2:45, a friend hits the alarm bell, and police are only able to remove them from the train at 3:45. The station remained closed for some time after.
Police confirmed that as soon as a protestor is on the train, the electricity has to be shut down for the entire line.
Various train disruptions had shut down the DLR for most of the day, forcing arms dealers to catch buses, taxis, and even walk to the exhibition.
