UPDATE: Sharon has been found safe and well.
Police have released a still image from CCTV footage showing a woman from Bolton who has been missing for four days.
Sharon Vickers, 61, was last seen at around 9.30am on Tuesday, July 28, on Knutshaw Crescent.
The day before, she was spotted by cameras entering the Decathlon store on Trinity Street in the town centre.
Detectives investigating her disappearance say she bought a tent and is believed to have had it with her the day she was last seen.
They have published an image of her entering the Decathlon shop, as well as a picture of a similar tent.
Officers are concerned she may not have her medication with her - and could quickly become unwell and confused if it is not taken.
Sharon is white with short grey hair. She is 5ft 1ins tall and walks with a limp on her left leg.
She was last seen wearing a lilac coat with a white trim and had a red shopping trolley.
Officers say they are becoming increasingly concerned for her welfare.
Anyone with any information should contact police on 0161 856 5620.
