Police said Thursday that there is a "threat situation" at a movie theater in a town in southwestern Germany which probably involves a weapon.

Police spokeswoman Christiane Kobus said she couldn't give further details of what was happening at the Kinopolis movie theater in the town of Viernheim.

She would not confirm unsourced German media reports that an armed man had entered the movie theater and fired at least one shot.

Norbert Schaetzle, a spokesman for police in the nearby city of Mannheim, said the police force there was not directly involved in the incident, but had sent officers to support their colleagues in the town.
