A river is being searched for missing mother-of-five Sarah Wellgreen, whose disappearance is being treated as a potential murder.
Kent Police tweeted that marine officers had begun searching the River Darent in Dartford town centre.
Ms Wellgreen was last seen on 9 October and reported missing two days later.
Searches began near her home in New Ash Green, near Meopham, but were extended to Dartford after the inquiry became a murder probe.
Officers have searched drains and used a drone around the Kent town.
Last week a man was arrested and bailed until 16 November pending inquiries.
Ms Wellgreen, 46, has not been in contact with her family since she was last seen in the Bazes Shaw area of New Ash Green, and has missed one of her children's birthdays.
Her car was at her home address and there have been no transactions on her bank or credit cards.
The only item missing from her home was her phone.
She was regularly seen around the Bazes Shaw area with her young children, but commuted to Portsmouth where she worked in a beauty salon.
Searches coordinated by New Ash Green Village Association have also continued on Saturday and appeals have gone out for more volunteers.
Det Supt Paul Fotheringham has said it was "entirely out of character" for Ms Wellgreen to go missing.
He said: "Sarah has disappeared without a trace."
