POLICE investigating the disappearance of Bronwyn Davies have released CCTV stills of potential witnesses seen in West Drayton.

They want to trace the people pictured and speak to them.

The stills show nine people walking along the same section of the Grand Union Canal towpath within an hour of the last confirmed sighting, at 10.28 on Thursday, January 1, of 60-year-old Mrs Davies.

She had been walking along the north towpath alongside John Guest Ltd after leaving her West Drayton home early on New Year's Day.

She was reported as missing later that day by her daughter, Ciara, when she failed to return home.

Mrs Davies regularly walks the same route and around the Packet Boat Lane area and marina with the family dog, Beth. She is well known in the area to other dog walkers and joggers.

Concerns for her welfare are increasing as she is Type 1 diabetic, and has no insulin with her, nor an inhaler which she uses regularly for asthma.

Mrs Davies is described as 5ft tall with grey hair, which is pinned up, making it appear short. She is of a slim and frail build and has green eyes.

She was last seen wearing a black rain mac, cream/grey woolly hat, navy blue wellington boots with a distinctive white dog pattern and was holding a black back pack and Tesco 'Bag for Life' carrier bag.

It is not believed she has any money or phone with her.

Det Sgt Andy Grant, said: "We are appealing to the members of the public shown on the CCTV stills to come forward and speak to us as they may hold valuable information which may assist us in our inquiries.

“With no further confirmed sightings of Mrs Davies since her disappearance, it is crucial we piece together any witness accounts to enable us build a clearer picture of her next movements.

"It is possible she may be in a disorientated state, due to lack of essential medicine, food and warmth.

“She may be seeking shelter and warmth on public transport or other areas or shelters open to the public.

“I want everyone to remain extra vigilant as Mrs Davies is particularly vulnerable, due to having no access to her medication."

Mrs Davies's daughter, Ciara, 31, said: "Mum, please contact me or call 999, just to let us know you are OK. We miss you so much.

“Please come home mum, we are worried sick about you. Everybody here in London, Dublin, Belfast and Italy are thinking of you."
