A 15-year-old British grammar school boy has been convicted of inciting an internet friend to murder him.

The boy, who can be identified only by the pseudonym John, invented a cast of characters in a chat room as part of a plan to commission his own murder. Some of his inspiration came from James Bond films and the science-fiction blockbuster Men In Black.

He was 14 when he fell in love with Mark, a boy two years older, and adopted the guise of a female secret service agent to order his friend to stab him in an alleyway.
