German spy Josef Jakobs was executed on the Tower's rifle range by an eight-man military firing squad on 15 August 1941. The Tower has also held numerous 20th Century prisoners. The most famous were the Kray twins, who were detained in a cell in 1952 after assaulting a corporal and absconding from their military unit. The Sun has their mugshots.
