The younger brother of Yorkshire Ripper Peter Sutcliffe believes his sibling should have been hanged for his 13 murders.

Former used car salesman Carl Sutcliffe, 58, said Peter told him he never needed mental health treatment.

The Ripper, who now calls himself Peter Coonan after taking his mother’s maiden name, was convicted of 13 murders and seven attempted murders in 1981. One of his victims was Huddersfield prostitute Helen Rytka.

Sutcliffe had been held at the high-security Broadmoor hospital until last week.

A mental health tribunal last December found he no longer needed specialist treatment and he was transferred to Category A Frankland Prison in Co Durham, saving taxpayers £250,000 a year.

Speaking to the Sunday People, Carl said Sutcliffe, 70, had never apologised to his family for what he’d done.

He said his brother didn’t deserve to live and added: “I’ve always had the view that people like him should be executed and I’ve told him so a few times.

“He didn’t respond to that. He probably did not want to hear that from me.

“I don’t think I can forgive him for what he’s done. Men hitting women is my pet hate, but to kill them – and with a hammer? What he did was disgusting – despicable.”

During his trial, Sutcliffe claimed to have heard voices that ordered him to kill his victims.

Sutcliffe now fears for his own safety in prison.

He told Carl in a telephone call: “I’m diabetic, I’ve got gallstones and I’m nearly blind.

I might be attacked and killed.”
