Police searched the canal as part of their continued enquiries into the whereabouts of a missing man.
They are reappealing for information and have released a new picture of Gareth Parker, 33, who left his home address in Barley Cop Lane in Lancaster at around 10pm on January 15.
He has not been seen since then and officers and his family are growing increasingly concerned for him the longer he is missing.
When he left the house, he was wearing a thick, padded white hooded top, grey tracksuit bottoms with bright orange stripes on the sides and black trainers.
He was also carrying a grey and black duffel bag, potentially containing an unknown change of clothes and some other personal belongings.
Gareth is described as white, of stocky build, with brown eyes and around 5ft 8ins tall.
Call police on 101.
