An Aussie cop spent five months in the slammer because his “vindictive, cancerous” ex — a police clerk — falsely accused him of rape, he said in a new interview.

Daniel Jones, 31, said authorities blindly believed the woman’s allegations against him, Australia’s “60 Minutes” reported this week.

Jones, a former Australian Federal Police dog handler, reportedly met his then-20-year-old girlfriend, Sarah Jane Parkinson, through work at Queanbeyan Police Station in 2011.

After a few months, the young couple became engaged and made plans to move into a new home in Canberra, according to the news program.

But on moving day, Parkinson reportedly told colleagues at the police department that Jones abused her.

“I’d just built a house and she’d moved in with me, everything was going well,” Jones told Australia’s “60 Minutes” in an interview that airs Sunday.

Jones maintained he was never violent with his fiancée, but police went ahead and brought charges against him.

“I had everything going right, and in that instant, everything just went to s–t,” said Jones, who said he now believes Parkinson was trying to obtain control of their new house.

A shaken Jones returned to the home he now shared with Parkinson, who assured him their law enforcement colleagues were just being overprotective, according to the news program.

But Jones said his fiancée’s lies only escalated, culminating when she told cops he raped her, the outlet reported. He was placed behind bars at a maximum-security prison in 2014 while investigators looked into the allegations, the report said.

“The first night, I cried myself to sleep,” Jones told the program.

It wasn’t until five months later that Jones was cleared and he was allowed to leave the prison, he said.

The probe determined there were multiple inconsistencies in Parkinson’s account. She was sentenced in January to 37 months in prison in connection with the bogus accusations, The Australian reported.

“She’s a lying, vindictive, cancerous woman,” Jones said.
