Search teams are continuing to comb the River Blackwater for missing Co Armagh woman Dolores Hughes.
A specialist team from Lough Neagh Rescue, under the direction of PSNI, are among those involved in the search of the river around the Moy area.
The search began on June 6 and has now entered its fourth week as teams desperately try and recover any clues around Ms Hughes’ disappearance.
A spokesperson for Lough Neagh Rescue (LNR) said: “LNR wishes to place on record our thanks to all those agencies who are involved in the search and to all the members of the general public, as well as the missing persons family for the hospitality shown to the crew under the current circumstances.
“LNR would also like to remind all members of the general public who are helping with the search, to remember the importance of water safety and to never search alone.
“If you find yourself in difficulty or spot anything out of the ordinary, please contact the police immediately on 999 in an emergency, or 101 in a non emergency.
“We would ask everyone to keep the family of the missing person in their thoughts and prayers during this difficult time.”
