A police whistleblower has accused the Home Secretary of ignoring warnings of an alleged child sex abuse cover-up.

Harry Bunker, 72, claimed Theresa May failed to reply when he wrote to allege two senior South ­Yorkshire Police officers protected paedophile pals during the 1970s.

The letter – seen by the Sunday Mirror – accused the pair of trying to sabotage one investigation where a dad admitted raping his daughters.

The retired detective said he was warned of “dire consequences” when he threatened to expose his bosses.

He said: “What went on in the force then was a scandal. For it to be ignored now is just as bad.”

Mr Bunker told how he wrote the note in January 2014 in the wake of the Rotherham scandal, where 1,700 girls were abused by Asian gangs.

The two officers he named – one now dead and one in his 90s – were not connected to those cases.

But he said: “It became an open secret that both those senior officers were against investigating sexual crimes against children.”

Mr Bunker called for an inquiry adding: “It still makes me angry.”

He claimed Shaun Wright – then Police and Crime Commissioner before resigning over the Rotherham scandal – also ignored the letter.

An aide of Deputy PM Nick Clegg acknowledged a third copy.

South Yorks Police “encouraged Mr Bunker to report his concerns.”
