The Bulgarian authorities have frozen around 14 million euro ($16 million) and blocked money transfers in relation to an ongoing investigation of alleged misuse of EU funds, prosecutor general Sotir Tsatsarov said. The sum was frozen on the basis of information gathered by State Agency National Security and in accordance with the country's anti-money laundering act, Tsatsarov said during a news conference in the city of Ruse held on Monday in relation to the brutal murder of local investigative journalist Viktoria Marinova, anchor and administrative director at TVN-Bulgaria channel. A video file of the news conference was published on the website of local broadcaster Nova TV. The probe of suspected misuse of EU funds was launched following a signal by deputy prime minister Tomislav Donchev, based on an investigation of local private media outlet Bivol.bg. On September 13, two journalists - Dimitar Stoyanov from Bivol and Attila Biro from Romanian investigative platform Rise Project were detained by Bulgarian police in a field south of Sofia as they were attempting to gather evidence on the burning of documents allegedly related to a misuse of EU funds by local companies connected to Sofia-based construction company GP Group.
