US authorities believe money taken from a Malaysian state fund was used to finance The Wolf of Wall Street
Actor Leonardo DiCaprio has been in communication with the US Department of Justice regarding allegations that funds stolen from a Malaysian development fund were used to finance the 2013 film The Wolf of Wall Street.
It was reported in July that stolen money may have been invested in the film which DiCaprio played the lead role in.
A spokesperson confirmed to the Financial Times that he sought to clarify whether he or his environmental foundation "ever received any gifts or charitable donations directly or indirectly related to these parties, and if so, to return those gifts or donations as soon as possible."
In July the US justice department began the process of attempting to seize more than $1bn worth of assets acquired with money stolen from a Malaysian sovereign economic development fund. The fund is subject to five international investigations.
It has been alleged that up to $6bn was misappropriated from the fund - and that the money was used to sustain the lavish lifestyles of a number of individuals who are connected to Malaysian prime minister, Najib Razak.
US attorney general, Loretta Lynch said stolen money was used to contribute to the funding of Martin Scorsese's Oscar nominated The Wolf of Wall Street and to buy artwork worth more than $200m, including works by Van Gogh and Monet.
The movie star had been called on by Bruno Manser Funds, a forestry charity, to either resign as a UN Messenger of Peace or renounce any connections to individuals involved in the scandal.
Malaysian businessman Jho Low and stepson of Malaysian prime minister Riza Razak were both thanked by the actor when he won a Golden Globe for his role in the film - both individuals have been named in lawsuits connected to the scandal.
Mr Razak is a co-founder of Red Granite Pictures, who produced the film.
The spokesperson added that he and his foundation will continue to co-operate with US authorities.
Mr DiCaprio has not been accused of any wrongdoing and a UN spokesperson has expressed the organisation's continued support of both him and his foundation.
