Oleg Deripaska is under scrutiny for links to money-laundering, bribery, racketeering and murder, US Treasury sources told the publication, reports New York Post

Russian oligarch Oleg Deripaska's $42.5million mansion on New York's Upper East Side has been seized by the US government as part of sanctions placed on the 50-year-old who cooperated with the Paul Manafort investigation, New York Post reports.

The aluminium billionaire – who has the likes of Rusal, Basic Element, En+, Russian Machines, Evrosibenergo, GAZ Group, B-Finance and the Kuban agricultural holding under his name – is under scrutiny for links to money-laundering, bribery, racketeering and murder, US Treasury sources told the publication.

It means any American companies engaging in business with him must cease operations by November 12, extended from the original October 23 deadline reports Crime Russia.

Despite the freeze on his Big Apple home, Deripaska - worth 2.8billion - had reportedly arranged for Roman Abramovich's ex-wife and their children to live there.

Dasha Zhukova, a socialite and friend of Ivanka trump's, is the daughter of another Russian oligarch – Alexander Zhukov – and resides at the property with son, Aaron Alexander, and a daughter, Leah Lou.

Both of her children with the Chelsea Football Club owner were born in the US and all three residents are American citizens.

The home is a double-wide, five-story townhouse that was owned by late international art dealer Alec Wildenstein and then-wife, Jocelyn Wildenstein before it was bought in 2008.

Perhaps complicating the matter, the family are close to Ivanka Trump and have been seen on vacations to the likes of Aspen, Croatia and Russia with US President Donald Trump's daughter and son-in-law Jared Kushner, a Senior Adviser to POTUS.

However, Zhukova and her children may not have to go far. It was reported by Page Six that her former spouse was building a mansion comprised of four townhouses for her on East 15th and 75th Street. It means he's transferring $92million in assets over to the woman he divorced amicably in 2017, reports the Post.

Abramovich himself worth $8.7billion has been the subject of recent rumors he's selling the soccer club and last month lost a High Court battle with Vladimir Potanin and Deripaska over selling his stake in a mining company Norilsk Nickel.

As well as the Manhattan property on 11 East 64th St – nearby a $90million home owned by Ukraine's Len Blavatnik - Deripaska's Washington DC property has also been claimed and FBI is also looking at his assets abroad, the report states.

Deripaska has been asked to give up operations on some of his possessions in Europe to avoid sanctions being imposed on them too according to the insiders.

Known to be friend of Vladmir Putin, Deripaska told FBI and the United States Justice Department that their claims were 'preposterous' when they tried to flip him against his country's government, and his former business partner Paul Manafort, according to a recent New York Times report.

He was one of at least six wealthy Russians questioned in 2016 about Manafort, who was convicted of hiding millions in payments from the Russia-friendly Ukrainian government.

Deripaska is a friend of President Vladmir Putin and reportedly told FBI and the United States Justice Department their claims were 'preposterous' when they tried to flip him against Russia

A US special counsel investigation of alleged ties between Donald Trump's presidential campaign and the Kremlin uncovered Manafort's tax-avoidance schemes and efforts to lobby government officials on behalf of Ukraine.

Deripaska came into play just two months after the FBI began looking into Russian election interference. American spy agencies later concluded Russia had hacked Democratic Party emails whose public release was devastating to Democrat Hillary Clinton's White House ambitions.

Trump has claimed the 2016 campaign season sparked a Clinton-funded plot using shaky Russian intelligence sources to build an opposition research file that the FBI used in its probe.

Deripaska did not surrender any incriminating information about Manafort, a man who was formerly among his business associates but now counted among his enemies. An anonymous source said he told the Russian government that the FBI and Department of Justice had approached him.

Deripaska reportedly split from wife Polina Yumasheva, the granddaughter of former Russian President Boris Yeltsin, whose inner circle is referred to as 'the family' by outsiders.

This year Deripaska also reportedly became a dual citizen of Cyprus, purchasing the 'golden visa' following failed previous attempts to become an EU citizen due to his alleged money laundering activity in Belgium.

The inquiry was dismissed in 2016.
