A 76-year-old man has admitted drugging and sexually assaulting several boys at a children’s summer camp. John Ruben laced sweets with tranquillising drugs and attacked two children after asking youngsters to play “a sweet game”, Leicester Crown Court heard. It comes after a number of children fell ill at Stathern Lodge on Canal Lane in Stathern, near Melton Mowbray in Leicestershire on Sunday 27 July.
