Police have re-created the moments after the final confirmed sighting of Clare Kenneford, the Watford woman who went missing a month ago.

The 42-year-old mother of three, also known as Frances, has a bi-polar disorder and was last seen on a CCTV camera shortly after she left her boyfriend's house in St Albans Road, Watford on Tuesday, April 21.

Using a Hemel Hempstead PCSO who resembles Ms Kenneford, Hertfordshire Constabulary today reconstructed her last known moves for a film which will be distribute over the internet.

Detective Inspector Justine Jenkins said there had been no confirmed additional sightings of Ms Kenneford.

She said: “People are ringing us for all the right reasons and we are following up everything that comes to us but in some cases we have been able to say it's not actually her by using CCTV footage.”

She added that it was getting more and more likely that Ms Kenneford was outside of Watford.

She said: “Locally she was so well known you can assume someone would have seen her by now. It's difficult to say where to look though as we have had no positive sightings anywhere.”

Police communications officer Olivia Finucane said further leaflets would soon be circulated in the area and that large notices would be placed in stations including Watford Junction, London Euston, Milton Keynes and Manchester.

Further coverage has been arranged with magazines and national television stations and milk cartons with details of the case are set to arrive soon.

Anyone with information on Clare's whereabouts should telephone Detective Inspector Justine Jenkins, from the missing persons unit, on 0845 3300222.
