Anti-corruption officials have detained a chief Romanian prosecutor for questioning.
Alina Bica heads a government department investigating mafia,organized crime and terrorism.
She is accused of abusing a previous role on a ministry of justice committee by approving a government payment that was overvalued by 60 million euros.
The case is part of an investigation that so far extends to two of Bica’s former colleagues as well as at least one businessman and an ethnic Hungarian MP.

Klaus Iohannis said during his election campaign that he was determined to tackle corruption, which is rife in Europe’s second poorest nation.
Data from prosecutors showed 1,007 people have been convicted for corruption and related offences in Romania so far this year, including 85 ministers, parliamentarians, mayors, judges and prosecutors.
