A suspect has reportedly been arrested in connection with the rape and murder of a Bulgarian journalist, who had recently highlighted possible government corruption.
The individual being held over the killing of Viktoria Marinova is a “Romanian citizen with a passport from Moldova”, according to unconfirmed reports from Bulgaria's interior ministry broadcast on national radio.
Ms Marinova, 30, had hosted a show last month reporting on two investigative journalists who had been detained for their work surrounding a suspected fraud involving European Union (EU) funds.
The presenter’s body was found dumped in a park in the city of Ruse, close to the banks of the Danube River on Saturday.
Following the programme hosted by Ms Marinova, Bulgaria’s interior ministry said prosecutors were investigating GP Group, a large construction company alleged to have misused the EU money, and froze 14 million euros (£12 million) in assets.
While the reporter did not appear to have been intimately involved in uncovering the alleged fraud, her show touched on a sensitive subject in Bulgaria, where corruption is endemic.
Early on Tuesday, volunteers combed bushes and ground in the park where Ms Marinova's body was found in an effort to find clues that could help police.
Local had people observed a vigil overnight on Monday, where flowers and lit candles were laid in front of her image.
European leaders have expressed shock at the killing.
Margaritis Schinas, spokesman for European Commission president Jean-Claude Juncker, said the commission expected “a swift and thorough investigation” that would “bring those responsible to justice and clarify whether this attack was linked to her work”.
He quoted Mr Juncker as saying previously that “too many” journalists are being intimidated, attacked or murdered and “there is no democracy without a free press”.
The German has also government sharply condemned the killing, with its foreign ministry saying it was imperative there was a fast investigation into the “horrible event”
Bulgarian interior minister Mladen Marinov insisted on Monday there was no evidence to suggest the killing was linked to Ms Marinova's work.
