Exclusive: Notorious Serial Rapist ‘Caught Carrying Knife’ in Public

Notorious serial rapist John Alan Wilde has faced a Sydney court hearing to challenge police allegations he was caught carrying a knife in a public place.

Mr Wilde, 56, who was convicted of raping multiple women at knifepoint in the 1980s and 1990s, was charged after police found a serrated blade, a roll of silver duct and a length of rope on his motorcycle in May 2017.

Mr Wilde, who is representing himself, told Bankstown Local Court that police had “no probable cause” to search his Harley-Davidson motorcycle that night.

“If their search was legal and their concerns were paramount why wasn’t I arrested straight away? Why wasn’t I charged straight away?” Mr Wilde said.

Mr Wilde came to the attention of police after a random licence plate check deemed his motorcycle registration to be out of date.

Constable Jared Olaussen gave evidence that when he entered in the offender’s details, there were a number of warnings in relation to knives.

He noted Mr Wilde’s criminal history also appeared.

“I read the criminal history in regards to the sexual assaults and the situation in which it happened,” Const. Olaussen said.

“I asked him if he had anything which he shouldn’t have. He said ‘I may have a knife’. He was pretty calm before that. When we spoke about the knife, his demeanour changed.

“He became nervous. His speech sped up. He stuttered twice during that time.”

But Mr Wilde argued, “could it be that I wasn’t nervous but worried that it could be misconstrued, that I had a knife in my hands for illegal purposes?”

The 56-year-old has pleaded not guilty to one charge of carrying a knife in a public place.

“I knew I had done no wrong. There is no crime in looking at a knife shop or swords, yet police are trying to infer that was grounds enough to conduct their search, and on that basis I argue that their search be deemed inadmissible and I then have no case to answer for.”

Police will allege when questioned on the side of the road, Mr Wilde told officers the knife was for cutting up fruit, yet there was no fruit located on the motorcycle.

He later changed his evidence that the serrated blade was for buttering bread.

Then when questioned by police as to why he had a roll of duct tape, he said it was for fixing his bike, yet there was no wear and tear on the two-wheeler, and it was deemed to be in excellent condition.

Mr Wilde is now living under strict supervision in western Sydney, after his interim high-risk sex offender supervision order was extended in November for a further two years.

The convicted rapist had been under the supervision order since his last release from prison in 2013.

This most recent arrest came just five weeks after his extended supervision orders were relaxed, after spending almost three decades behind bars for a series of monstrous attacks.

Mr Wilde was convicted of his first rape in 1981, after forcing his way into a woman’s home.

Three months after his release on parole in 1983, he struck again, this time attacking a mother in front of her two children.

The terror continued in 1991, just 13 days after his release from jail with the rape of a 23-year-old.

Each time his victims were threatened with a knife, bound and gagged.

On Monday, Mr Wilde argued police had no probable cause to search him that May night, and the charge and reinstated control orders should be dropped.

The hearing will resume in May.
