Mystery Substance Discovered in Main River in Frankfurt

On Saturday, impurities in the Main were discovered in Frankfurt. The substance found is a mystery to the investigators.

Operation for the Frankfurt police: On Saturday, a greyish-brown substance was discovered in the water of the Main. Streaks of the substance have been found throughout the city since the morning, the police said. It is not yet clear what the substance is.

The police also used a helicopter, but the cause of the pollution could not be clarified. The officials suspected the crew of a goods motor vessel. However, this was not confirmed by investigations on board. Since the substance is only floating in the Main in small quantities, no elimination measures need to be taken.
