Jammie waylett A judge has sent a cast member of the " Harry Potter " films to prison for taking part in rioting that flared across England last summer. Judge Simon Carr sentenced Jamie Waylett , who played Hogwarts bully Vincent Crabbe in six of the films, to two years in jail. Prosecutors said Waylett was part of a small gang that took part in the riots in north London on Aug. 8. A jury at London's Wood Grenn Crown Court found Waylett guilty Tuesday of violent disorder, but acquitted him of another charge of intending to destroy or damage property with a fire bomb he was holding. The 22-year-old had already admitted handling a bottle of stolen Champagne from a supermarket during the riots. Waylett has a previous conviction for growing marijuana.
