Guildford pub bombing case papers lost in police blunder
Five boxes of documents on the 1974 Guildford pub bombings have been destroyed, Surrey Police have admitted.
The blunder was blamed on a driver who left them in the wrong place, a pre-inquest review at Woking Coroner's Court heard.
A coroner is considering whether to resume a full inquest into the IRA attacks.
The original proceedings did not conclude after the Guildford Four were wrongfully convicted over the bombings, which killed four soldiers and a civilian.
They were handed life sentences, but had their convictions overturned in 1989, in one of the UK's most well-known miscarriages of justice.
Jeremy Johnson, representing Surrey Police, said: "It's known that five boxes of material have been destroyed, but they contain documents which, at least to a large extent and possibly to a complete extent, are copied elsewhere."
Coroner Richard Travers said he would hand down his judgment on whether to resume a full inquest on January 31.
