Trevor Lock, the policeman who was taken hostage in a siege on the Iranian embassy in London in 1980, has died aged 85, his daughter has confirmed.
PC Lock was freed along with 24 other hostages after a six-day stand-off between members of a dissident Iranian group and the SAS.
It later emerged he had tackled the leader of the gunmen and saved the life of an SAS soldier.
He was awarded the George Medal, which recognises outstanding bravery, for his actions.
