Sexual predator who drugged and raped straight men could have more victims police believe


POLICE fear a "dangerous sexual predator convicted of drugging and sexually abusing two straight men may have other victims too embarrassed to come forward.

Luiz Inacio Da Silvaneto, 36, of Wandsworth, London, was found guilty at Oxford Crown Court on Friday of two counts of administering a substance with intent to overpower to allow sexual activity, one count of rape and two counts of causing a male to engage in penetrative sexual activity without consent.

Detective Inspector James Holden-White of Thames Valley Police said: “Luiz Inacio Da Silvaneto (below) is a sexual predator and a very dangerous man.

“He used what presents as a well-practiced modus operandi; targeting men, administering a substance to incapacitate and overpower his chosen victim, and then engaging in sexual activity with them.

"“Da Silvaneto deliberately targeted heterosexual men whom he believed would be especially unlikely to report the offences to police.

"It is possible there are other victims too embarrassed to come forward.

“We are keeping an open mind as to the possibility that Da Silvaneto has committed other offences."

The Met Police issued a similar appeal due to him living in the capital.

On November 10 2021, the first victim was with Da Silvaneto at a property in Middle Barton doing maintenance work.

After they both drank some alcohol, the lost consciousness and later awoke to find Da Silvaneto sexually assaulting him.

On December 10 2021, Da Silvaneto targeted his second victim who was enjoying a night out in Chelsea.

The victim tried to organise a taxi, when he encountered Da Silvaneto driving a vehicle.

The victim cannot remember any further details other than being forced to consume a shot.

When he awoke the next day he was in an unknown property, which police established was the property in Middle Barton.

This victim had been drugged and raped.

The prosecution said Da Silvaneto had spent the earlier part of the evening approaching males in public toilets where he also set up covert recording.

Ahead of trial Da Silvaneto, who claimed in court it was consensual sex, admitted seven counts of possession of drugs of class A to C.

He was found not guilty of one count of kidnapping, one count of committing an offence with intent to commit a sexual offence and one count of administering a substance with intent to overpower to allow sexual activity.
