Manx Wildlife Trust calls it a 'pollution incident'
More than 60 fish and invertebrates have been found dead, after what's thought to be a 'pollution incident' at Summerhill glen.
Manx Wildlife Trust says its Education and Biodiversity Officer made the discovery whilst on an trip with a school group yesterday.
Department of Environment, Food and Agriculture staff were "quick to attend", MWT says, took water samples, and are now "investigating the pollutant and the cause."
