Fish poisoned in Fribourg river
Over 300 fish were killed after a man released a poisonous cleaning agent into a stream in canton Fribourg.
Police say a 43-year-old was cleaning tanks when the agent leaked into the creek through the sewage system.
The river turned red and hundreds of fish died.
The fire department installed a barrier to try to stop the rest of the poison and pumped out the stream.
The man is being investigated.
