A group of people dressed up as zombies have taken part in an 'invasion' of Leicester, after the council admitted it was unprepared for an attack by the living dead.About 150 people in horror make-up took part, according to organiser James Dixon, who came up with the idea after a "concerned citizen" used a Freedom of Information request to ask how the council would tackle a zombie attack.Passerby Chris Porter, who filmed the invasion, said people were getting on with their normal routine when a steady horde of zombies "came lumbering into view".
