In July, the institute investigating communist crimes wrote to the general prosecutors calling for Visinescu to be prosecuted for six deaths. It says it will give a total of 35 files about former commanders to prosecutors.
The institute said it "welcomed the historic decision" and urged the prosecution "to continue to concentrate its efforts on identifying those responsible for crimes and political abuses in the communist period."
In August, Visinescu cursed a cameraman and lunged several times at journalists who were seeking reaction to the accusations against him. Since then, there has been public debate about the era, with many people speaking in favor of moves to punish former prison commanders.
President Traian Basescu and Prime Minister Victor Ponta have both said that former commanders should face justice for crimes they may have committed.
About 500,000 Romanians, priests, teachers, peasants, doctors and diplomats were condemned as political prisoners in the 1950s as the Communist government sought to crush all dissent. One-fifth of those who were imprisoned died due to the harsh conditions, historians say.
