Search and rescue divers have joined the search for a missing woman last seen five days after not turning up to work.
Shannon Canning, 24, has not been seen since she left her home in Keswick Court, Lancaster, in the early hours of Friday morning.
She had failed to show for her shift at Tipple Bar in the city centre the next day, with police launching a desperate search operation.
Police say the young woman's disappearance is "out of character" and that they are "increasingly concerned" for her welfare.
In recent days, police have been seen conducting land searches around the Ridge Estate and city centre areas.
Now police divers have joined the search operation in the River Lune in the city centre.
It is believed she was wearing a light blue vest crop top, a hoodie, pants, and white Nike trainers when she was last seen.
A spokesman for Lancashire Police said: "We are asking for your help again as we look to find Shannon Canning who is missing in Lancaster.
"She hasn’t been in contact with any of her friends and family since leaving her home.
"We have a dedicated search and investigation team in place who are working alongside partners from other agencies to find Shannon as quickly as possible.
"You will see an increased presence of police officers and specialist resources in Lancaster as we search for Shannon, in particular around the Ridge estate and city centre.
"A number of premises will be secured as we continue to piece together Shannon’s movements.
"Divers from the North West Underwater Search Unit will be searching in the area, while the Lancaster Area Search and Rescue team and the Lancashire Fire and Rescue Service are assisting with land and water searches.
"This is a missing from home enquiry currently but all lines of enquiry, including searches of specific addresses, speaking to members of the public, studying CCTV footage and digital enquiries, are being carried out.
"Anyone who thinks they might have seen Shannon since the early hours of Friday, May 19, or who have information which they feel could assist us in finding her, are urged to contact police.
