A man who claims police bullied him into changing his story to help jail three innocent men for murder thought officers would hurt him, a jury heard.
Known as the Cardiff Three, the men were jailed for murder but were later freed on appeal.
Mark Grommek told the Lynette White corruption trial at Swansea Crown Court that he had lived in fear and was “always looking over my shoulder”.
Eight ex-police officers deny conspiracy to pervert the course of justice.
Two other people deny perjury.
Grommek agreed that he had said the murder squad detectives had harassed him until he thought “they would hurt me and put me in prison”.
But he said on Friday that after he “broke” on 22 November 1988, and “gave the police what they wanted to hear, they could not do enough for me”.
The trial continues.
