Environmental officers last night appealed for help to find the polluter responsible for killing more than 35,000 fish in a river in Northern Ireland.
The Environment Agency admitted it has been unable to identify the source of the spill in the Six Mile Water, Co Antrim.
Agency staff have narrowed down the possible point of entry to two pipes coming from the direction of Mallusk Industrial Estate. They are carrying out pollution risk assessments on business premises on the estate in an effort to trace the leak.
More than 25,000 trout and around 10,000 coarse fish were killed in the incident on June 18.
Senior officials from the NIEA last night met with fishermen and other users of the Six Mile Water at a public meeting in Antrim — organised by the Antrim and District Angling Association — to discuss the impact of the fish kill.
Acting NIEA Chief Executive Dr Roy Ramsay said he was anxious to establish what happened.
He said anyone with information should contact NIEA Water Team on 02892 623238 or the Pollution Hotline on 0800 807060.
