Officials are investigating a pollution incident that has killed more than 1,000 fish in the River Callan at Armagh city.
The Northern Ireland Environment Agency (NIEA) said they received a report of dead and distressed fish in the waterway on Tuesday evening.
Inspectors traced the pollutant to a specific tributary upstream of Armagh city and a definite line of enquiry is now being followed.
At least 1,000 brown trout and 100 salmon are believed to have died in the incident so far and work is ongoing to assess the full impact.
An NIEA spokesperson said: "Statutory samples have been collected and evidence gathered with a view to initiating prosecution proceedings through Public Prosecution Service.
"The investigation, under the Water (NI) Order 1999 remains ongoing."
