The son of Turkish President Recep Tayyip Erdogan has been charged of money-laundering and bringing unauthorised money into the country.

Bilal Erdogan (35) is being interrogated by prosecutors in Bologna about the financial dealings. He is currently living in the city with his family and pursuing his doctorate at the Bologna campus of America’s Johns Hopkins University.

The probe came after Murat Hakan Uzan, a businessman and political opponent of the Erdogan family accused him of money laundering to the Italian authorities. He filed the complaint with Bologna public prosecutors after alleging that Bilal Erdogan has breached financial laws of Italy and bringing money without the knowledge of the authorities.  Manuela Cavallo, Bologna’s chief public prosecutor will investigate the claims of money laundering.

Uzan said that Bilal was accumulating  money in Italy and considered it a bolt-hole to avoid problems. He claimed that he had been oppressed by Erdogan regime.

Bilal Erdogan’s lawyer Giovanni Trombini said: “I have nothing to say. Trials should be held in court, not in the press.”

Following a corruption scandal in 2013, Bilal Erdogan moved to Italy said critics of the Turkish government.

In 2014, Telegraph reported a wiretapped conversation between two people – believed to be Recep Tayyip Erdogan and his son Bilal Erdogan leaked to the internet, in which both were heard talking about how to dispose large amount of money.

However both denied the claims and said it was fabricated.The conversation was disclosed in December 2013. Son of three cabinet ministers were apprehended after a probe.

Erdogan has interests in shipping business and oil tankers trade. Recently in December, Russian Prime Minister Dmitry Medvedev accused the Turkish leader including other Turkish officials for being involved in the illegal oil trade by ISIS. But he denied the claims for having no links in the trade, IBTimes reported.

“ISIS is an enemy of my country. ISIS is a disgrace. It puts my religion in a bad light. They don’t represent Islam and I do not consider them to be Muslims,” according to Bilal Erdogan.

Russia also considered putting economic sanctions on Turkey for shooting down a Russian war plane.
