A police officer hands out copies of the Order of Service during a memorial service held in St James Square, London, to mark the 30th anniversary of the death of WPC Yvonne Fletcher.

Family members joined friends and colleagues in remembering the officer, who was shot dead outside Libya's London embassy on April 17, 1984.

Nobody has ever been brought to justice for the killing. The family issued a statement saying it was "time this case was closed" but 30 years on they were no closer to obtaining justice.
