John McGranaghan

John McGranaghan was a Scottish underworld figure, known for being the arch rival of Glasgow boss, Arthur Thompson. According to McGranaghan, a businessman with links to the Glasgow underworld asked Thompson to have McGranaghan murdered, but instead a well-known Scottish boxer from Craigmillar was brutally stabbed to death in 1974, due to identity problems.

In 1981, John McGranaghan was sentenced to life in prison for rape and assault against three women, but was freed in 1991 after the appeal courts determined that his conviction had been a miscarriage of justice. He died of heart failure, at the age of 72.
