Police investigate other alleged attacks by rapist Luiz Da Silvaneto

Luiz Da Silva Neto was jailed for 22 years in 2022

Police are investigating further alleged crimes by a rapist who was convicted of drugging two men before sexually assaulting them.

Luiz Da Silva Neto was jailed for 22 years in 2022 after attacking the men in separate events at his cottage in Oxfordshire in 2021.

One of his victims has described their ordeal to BBC Crimewatch Live.

He said it had left him needing to "lay in a cold bath tub just to try and calm myself down".

"This is the worst experience I have ever survived or lived through. You want to digest it, but you can't," he added.

Det Insp James Holden-White believed Da Silva Neto targeted straight men as he thought they were more unlikely to come forward

Det Insp James Holden-White, of Thames Valley Police, said several people had "shown great courage in coming forward to report some further alleged offences".

He said he appreciated "how hard it is for any victims of offences like these to approach the police", but added the force had "dedicated officers who specialise in investigating sexual offences".

He said investigators were trying to identify a number of males who they believe encountered Da Silva Neto at his cottage and highlighted the period between 2018 and summer 2021 as being of particular interest.

Mr Holden-White said: "He is targeting straight men. And he is probably targeting straight men because he thinks they are particularly unlike to come forward."

'Monster'

Da Silva Neto lived in Wandsworth, London, but ran a bed and breakfast in Middle Barton, near Banbury in Oxfordshire, which is where the attacks on the two men took place.

The first victim drank alcohol with him at the property which he said "knocked me out instantly, like in 10 minutes".

He then "woke up in the middle of the night... that's how I saw what was going on. I couldn't speak. I just tried to mumble."

The second victim had been out in a club in Chelsea and woke up in the B&B, two hours away from home, police said.

"He remembered a man holding a tumbler of dark liquid to his mouth and encouraged him to drink it," the force added.

The man told Oxford Crown Court during the 2022 trial he was glad he had helped "break the chain and protect others from this monster".

Police are urging anyone with information to come forward, quoting Operation Jion.
