Fiona Nicol, who was a constable when she volunteered to police the game on her day off, said she had been scared of reprisals from the police hierarchy.
She told the BBC: “I thought they were trying to blame and scapegoat us and if the opportunity had come they would throw us to the wolves.
Ms Nicol was seen on CCTV trying to rescue 14-year-old Adam Spearritt, from Cheshire, by lifting him off the terraces before trying unsuccessfully to revive him.
She said she still believes she “didn't do enough to save him” and has never returned to a football stadium, even banning her children from going to football matches.

“People were just piled on top of each other and arms and legs. You couldn't get them out, you couldn't pull them without hurting them more.
“He was unconscious, he was limp, he could not help himself. They were coming up over the top of me and it was one of the fans as they were pulling up over the top of me, I was screaming at him to help me because I've still got hold of the boy's arm - I never let go of him.
“There was all that chaos going on around me and I was just focused totally on this boy.
“I didn't do enough, you see. How can you ever lose a child, that's awful. I didn't do enough to save him.”
