The parents of a public schoolboy who died after plunging into the Thames from a balcony opposite the MI6 HQ have accused the Met Police of 'victim blaming' and failing to properly investigate the circumstances of their son's death.
Zac Brettler, 19, plummeted from a luxury Thames-side apartment development in 2019 - with his fall captured on the MI6 building's CCTV across the river.
The teenager had become enamoured with wealth during his time at Mill Hill School in north London, an exclusive £30,000-a-year boarding school where many pupils were the children of Russian oligarchs.
In order to play up his connections, he had adopted multiple different identities, including that of a Kazakh man, a friend of Liverpool captain Virgil van Dijk and the son of a Russian oligarch.
Before the tragedy, Zac had spent the night with a wealthy businessman and the man's friend, the gangster Dave Sharma. Sharma - known as Indian Dave in underground circles - had previously been arrested in 2002 for a heroin smuggling operation and was linked to a consequent gangland murder.
CCTV and phone records showed that Sharma and the second man probably knew Zac had fallen from a fifth floor balcony into the Thames at just after 2am on November 28, The Times reported.
Sharma had messaged a friend at 10.30pm saying he had been 'heating up knives and cleaning the blood', before adding in a voice note: 'S**t's about to go wrong. Wrong!'

Zac's parents, Rachelle and Matthew Brettler, only found out about these messages from the police nearly two years after their son's death.
The couple, both 61, have now accused the Met of 'victim blaming' as they say they were too quick to pursue the suspicion that Zac killed himself.
'The omissions are highly suggestive of a degree of incompetence that it's very hard to get one's head around. You think, surely they can't be that bad,' Matthew Brettler, the director of a financial services company, told The Times.
'My major criticism of the police is that there was no smoking gun and that then required them to do the hard yards in terms of detective work and they never showed a real appetite for it.'
The couple also gave an interview to The New Yorker, which first reported the story.
Describing her grief, Rachelle said: 'I was living on that balcony with Zac, in my head. I literally had a stomach ache for months after he died, because you're having to digest grief.'
The heartbroken parents believe their son jumped from the building in an effort to save himself from what was inside.
They deny that he was suicidal - saying he emailed his mother on the night he died about booking a driving test and his overnight bag contained enough clothes to last several days.
And they have questioned why detectives did not interview key witnesses who knew what had happened in the run up to his death, according to The Times.
Two days before he died, Zac told a friend that someone had threatened his family and searched for information about witness protection on the same day, the newspaper reported.

Prior to his death, Zac was calling himself Zac Ismailov.
He told new friends that he had recently inherited his late father's fortune but he was being blocked from accessing it by his mother, who lived in Dubai.
He got to know wealthy businessman after they agreed to become prospective business partners.
The businessman then put Zac in touch with gangster Dave Sharma, who lived alone in an apartment at the Riverwalk development, in the hope he could give the teenager a home while he resolved his 'inheritance dispute.
Zac briefly lived at the apartment before returning to visit with the businessman on the night of his death.
Messages in the run up to Zac's death showed Sharma was getting more and more interested in the teenager's wealth, writing on the morning of the tragedy: 'I'm thinking f*** this little kid.'
The teenager was eventually found at the base of the tower block with a broken jaw - the cause of which could not be determined - and injuries to his hip, which smashed into the embankment wall, according to The Times.

Police reportedly only visited the apartment four days after his death - and did not forensically test smears resembling blood on the walls.
Sharma and the businessman were arrested for murder. He said he had spent parts of the night asleep, although this was later disproved by a log of calls and messaged, according to The Times.
He claimed that their last night with Zac had been an emotional one, where he had confessed to having a secret heroin addiction, the newspaper also reported.
No trace of the drug was found in his system by the pathologist and his parents deny that he would do this.
Poplar coroner's court recorded an open verdict in 2022.
Sharma was found dead in the same apartment in 2020 after an apparent drug overdose.

A Met Police spokesperson said: 'Our sincere condolences remain with Zac Brettler's family, and we understand the uncertainty about how their son died must continue to be the cause of unimaginable pain.
'Whenever someone dies unexpectedly in London, we have established policing protocols to follow, and the investigation into Zac's death was led by an experienced detective.
'The team worked hard to explore every possible hypothesis, which were shared with Zac's family, but ultimately we were not able to provide fuller answers.
'The case was also reviewed by specialist homicide detectives to ensure every line of enquiry had been exhausted.
'As with any case, we would always encourage anyone who they believes they have additional information or evidence to contact police. Any new information will be examined on its own merit by a team led by experienced detectives.'
