Updated: 12:31, Monday November 14, 2005
Police in Germany are investigating a plot to poison a lake which supplies drinking water to 4.5 million people.
Officers found several suspect containers in Lake Constance, in the south of the country.
The lake is shared by Germany, Austria and Switzerland.
A letter had been sent to the lake's managers which threatened to dump pesticides into the water.
Authorities are now examining the contents of the containers.
They say tests have shown it is safe to drink water from the lake.
