Facing a riot, even a mock one, is a frightening business, as reporter NATALIE BOWYER found out. Pictures: HELEN DRAKE. PETERBOROUGH Football Club have just lost at home to Norwich, and the fans are not happy. After making a barricade across a street outside the stadium, using cars and whatever else they can get their hands on, the 100-strong crowd becomes increasingly aggressive. More than 100 officers from Cambridgeshire and Norfolk police are mobilised to deal with the disturbance. Quickly, the situation escalates into a full-blown riot with fans hurling bricks, tyres and petrol bombs at officers. Luckily, this is only a police training exercise but from the roof of a Huntingdonshire RAF building, it looked and sounded real.
