Police searched the canal as part of their continued enquiries into the whereabouts of a missing Lancaster man.
They are reappealing for information and have released a new picture, right, of Gareth Parker, 33, who left his home in Barley Cop Lane at around 10pm on January 15.
He has not been seen since then and officers and his family are growing increasingly concerned for him.
When he left home, 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 a change of clothes and other personal belongings.
Gareth is described as white, of stocky build, with brown eyes and around 5ft 8ins tall. Contact police on 101.
