Environment officers are investigating after printer cartridges were dumped in a stream in Kent.
Student Toby Isaac took this picture after stumbling across the damage while he walked his dog.
Car tyres and magenta printer ink had been dumped in the brook at Broad Oak, Canterbury, turning the water bright pink.
The Environement Agency was called in to clean up the mess and they're hopeful there won't be any lasting damage to wildlife.
They're awaiting the results of lab tests but believe the substance to be magenta copier toner.
