Detectives investigating the disappearance of Lindsay Birbeck are appealing for information to find a dog walker who was in the area she was last seen.
CCTV footage showed Lindsay, from Huncoat, around 4.10pm on Monday the 12th of August in the Burnley Road area walking in the direction of Accrington.
Police say they've been carrying out a number of enquiries including house to house, CCTV and searches but so far there is no trace of the 47-year-old.
Officers believe Lindsay may have walked from Burnley Road into a wooded area known as The Coppice.
Police are particularly keen to trace a dog walker who was in the Peel Park Avenue area between 4-5pm and who may have seen Lindsay.
He is described as a white man, aged in his late 40s, 5ft 6in tall, of medium build with short dark hair and wearing glasses. He is believed to have been wearing a dark jacket or coat and was walking a small black Labrador.
