Footage showed a man being quickly surrounded by several security guards and police in front of onlookers, before being led off the floor of Westminster Hall. Other mourners in the queue reacted to the incident, with the crowds in the hall appearing shocked. A Met Police statement said: ‘At around 10pm on Friday 16 September officers from the Met’s Parliamentary and Diplomatic Protection Command arrested a man at Westminster Hall following a disturbance. “He was arrested for an offense under the Public Order Act and is currently in custody.” The incident comes hours after King Charles and his siblings stood a silent vigil around Her Majesty’s coffin as the public passed quietly by. The queue to see the Queen lie in State grew so long earlier on Friday, it had to be stopped for several hours after stretching as far as Southwark Park. When the line resumed, the official tracker showed a wait time of up to 24 hours for those lining up to pay their respects.
