A leaflet drop is being organised in Dublin today as the search for missing woman Peggy Mangan enters its fifth day.

There have been several sightings of the 64-year-old grandmother who has Alzheimer's Disease.

She left her home in Terenure in the south of the city for a walk with her dog last Tuesday.

The last confirmed sighting is at the Charlestown Shopping centre in Finglas on the city's northside at 9.45pm on Tuesday.

Leaflet drops are being distributed at all major sporting events in the city today to try to jog the memory of anyone who may have seen the missing woman and her Cavalier King Charles spaniel.

Businesses - particularly in the Finglas area - which may have CCTV footage are being asked to examine it.

Over 300 volunteers have been searching since she disappeared and searches resumed this morning.

Anyone who can assist in the search is asked to go to the search control centre located at the DID Electrical Store in Finglas.
