The ex-banker husband of Kimora Lee Simmons was spotted this weekend for the first time since being subpoenaed two months ago in connection to a money laundering scandal in Malaysia.

Former Goldman Sachs banker Tim Leissner was seen taking an afternoon stroll with the fashion designer and their kids in New York on Sunday.

The couple beamed with happiness as their one-year-old son, Wolfe, peaked over the edge of his stroller. Kimora Lee Simmons' other son, six-year-old Kenzo, was also on the walk.

Leissner, 45, left his position as the Singapore-based chairman of Goldman's Southeast Asia operations in February as an investigation into a state fund unfolded.

In March, Leissner was subpoenaed by the US Justice Departments as part of the investigation into Malaysia's snowballing corruption scandal. 

People close to the matter, speaking on condition of anonymity, said at the time that Leissner, was called to testify relating to the payments scandal that surrounds Malaysian Prime Minister Najib Razak.

Based in Singapore as Goldman's Southeast Asia chairman, Leissner advised the state investment fund 1Malaysia Development Berhad, or 1MDB, for which Goldman Sachs received commissions for bond sales.

The state investment fund is now at the center of allegations of secret transfers of hundreds of millions of dollars to Najib's private accounts.

Najib has denied accusations of corruption, which have embroiled the government for months.

Attorney-General Mohamed Apandi Ali said in January the transfer was a gift from Saudi Arabia's royal family and that most of it was returned.

The 1MDB fund has denied any of its funds went to the prime minister. The parliamentary report did not name Najib or link any transaction from 1MDB to his private bank accounts.

Najib said the report showed the opposition's allegations against him were false, but that 'action will be taken if any evidence of wrongdoing is found'.

According to one AFP source, Leissner, a German national, was suspended by Goldman in January for violating company policies on a matter separate from the 1MDB case. Leissner then left Goldman in February.

The New York Post reported in February that the FBI were investigating all the fund's transactions due to money-laundering allegations in five countries.

Three bond sales for 1Malaysia Development Berhad in 2012 and 2013 amounted to $6.5billion.

Goldman Sachs took fees and commissions that totaled $593million.

Based on that figure, the bank received a cut of 9.1 per cent, when the typical amount is five per cent.

The family was based in Singapore until Leissner stepped down from his position with Goldman Sachs earlier this year

After Leissner stepped down from his position, the family was believed to be in Los Angeles. It is unknown as to why the family was on a walk in New York this weekend

'People are smelling something here,' Gary Swiman, head of compliance and regulatory consulting services at EisnerAmper, told The Post. 'This has been a disaster for Goldman.'

Late last year the US Federal Bureau of Investigation began investigating the accusations of corruption and money laundering.

Authorities in several other countries are also investigating the money flows.

Swiss authorities have said they believe $4billion may have been stolen from Malaysian state firms and have frozen millions of dollars in accounts linked to 1MDB.

At the beginning of February Singapore seized 'a large number of bank accounts' in its 1MDB investigations, vowing not to let the global banking hub become a refuge for illicit funds.

'Singapore is also cooperating closely with relevant authorities, including those in Malaysia, Switzerland and the United States,' said a joint statement from the Monetary Authority of Singapore and the police Commercial Affairs Department.

Leissner worked for Goldman Sachs for 18 years, and has yet to be charged with any offense relating to the state fund.

The fund was started in 2009 to bolster Malaysia's coffers, however it quickly took on a lot of debt.

In early 2015, it missed $11billion of payments it owed to banks and bondholders.

Kimora Lee Simmons, the former wife of hip-hop mogul Russell Simmons, is believed to be friends with the wife of the Malaysian Prime Minister.

Lee and Simmons split in 2006 after eight years of marriage and having two daughters together, Ming, 16, and Aoki, 13.

Lee married actor Djimon Hounsou in the summer of 2008 and the two had a son together, Kenzo. The couple separated four years later in 2012.

The businesswoman then began seeing Leissner, who she married in early 2014. Last year the two welcomed their son Wolfe.

Not long after the birth of Wolfe, Lee paid tribute to her husband in a Father's Day post on Instagram, describing him as the 'backbone' of the family.

'Thank you for being so selfless, without ego and nurturing to all of our kids!' the post said.

'Thank you for helping them realize the sky is the limit!! I couldn't have wished or hoped for anyone more amazing! We love you and appreciate you so much!'
