Officers are appealing to the public for help in tracing a man who has not been seen since Saturday and was reported missing on Sunday.
Christopher Mark Williams, aged 50, was last seen in the Primark store in Preston.
He is described as a white male about 5’ 10” tall, of slim build and with dark, short hair. He was wearing a brown patterned lumber type jacket with woollen collar, a red shirt underneath and dark jeans and black shoes.
Officers are growing increasingly concerned for his welfare.
Anyone with information that could help officers is asked to please contact 101.
