A body found in a field on the edge of north Dublin is believed to be that of missing pensioner Peggy Mangan.
Gardai said they were investigating the circumstances surrounding the discovery of a female at Ballymun Road in the Ballymun estate at about 3.30pm today.
The woman's remains were found by police close to the Ikea complex at Ballymun. They have since been removed to the city mortuary and the area has been sealed of for further forensic examination by Garda technical officers.
A massive search operation had been mounted after the 64-year-old grandmother, who suffers from Alzheimer's disease, went missing five days ago. And today leaflets were handed out at all major sporting events across the city in a bid to jog the memory of anyone who may have seen Mrs Mangan and her Cavalier King Charles spaniel.
She left her home in Terenure in the south of the city for a walk with her dog last Tuesday.
The last confirmed sighting was at the Charlestown Shopping centre in Finglas on the city's northside at 9.45pm on Tuesday.
Fianna Fail councillor in Ballymun Paul McAuliffe, who had helped with the search during the week, described the situation as tragic.
He said: "If it turns out to be the case that this body is that of Peggy Mangan, it is a desperately sad ending.
"There are lots of people who have elderly parents in the same position and those involved in the search said they hoped the community would them help out in the same way if they ever found themselves in such a tragic situation.
"This was a human response from a very good community."
The office of the State pathologist has been notified and a post-mortem examination will be carried out at a later date.
