Former French President Nicolas Sarkozy, was taken into custody on Tuesday due to allegations of receiving millions from the regime of Muammar Gaddafi in his 2007 election campaign, The Guardian reported.

Sarkozy is being questioned at Nanterre police station, in Paris, regarding a €50 million donation made by the Libyan regime, which is twice the amount legally permitted. French law also obliges candidates to declare the source of received funds.

The allegations of illegal campaign funding from Libya is not new as in 2013 an investigation was opened, yet no suspects were formally charged.

Three years later the case was brought back to the forefront when French-Lebanese businessman Ziad Takieddine, told Mediapart, an online investigative site that he had received a suitcase with money from Libyan intelligence chiefs to deliver in three separate occasions to Sarkozy and his former Chief of Staff, Claude Gueant Gueant.

Even though Sarkozy and Gueant denied the authenticity of the documents obtained by Mediapart, the French court had accepted them for later use. During the same year, Sarkozy was on trial over charges for suspected illegal overspending during his unsuccessful bid for re-election in 2012.
