Bulgarian officials said Wednesday authorities have arrested a suspect in the rape and murder of journalist Viktoria Marinova.

Chief prosecutor Sotir Tsatsarov identified the suspect as Severin Krasimirov, a Bulgarian citizen who was taken into custody in Germany.

Tsatsarov told reporters that so far investigators do not believe Marinova’s rape and killing was linked to her work, but rather was a spontaneous attack.

Krasimirov has been charged with rape and premeditated murder.

Marinova had investigated alleged corruption involving politicians and European Union funds. Her body was found Saturday in a park in the northern city of Ruse.
