DIVERS have returned to the river where Nicola Bulley's body was discovered.
Video shows specialist cops searching the water to try confirm the tragic mum's cause of death.
Police say Dr James Adeley, HM Senior Coroner for Lancashire asked them to conduct the investigative work.
The area is less than a mile from where Nicola was last seen on January 27, after a tip-off from two dog walkers.
Footage, taken by a local resident, shows officers wading through the water.
Nicola was deemed a "high-risk" missing person when she vanished due to a "number of specific vulnerabilities".

A spokesman for HM Coroner said: “The investigation will take time to complete to ensure that as complete a picture as possible of the facts concerning Ms Bulley's death is presented at the inquest.
"This will assist the family in understanding what occurred."
Nicola's disappearance after her mobile was found on a bench still connected to a work conference call.
Nicola's pet springer spaniel Willow was also found - but there was no trace still of the mum-of-two.

On Sunday February 20, Police searching for Nicola confirmed a body had been found less than a mile from where she was last seen more than three weeks earlier.
An inquest into her death is to be heard on Monday, June 26 at County Hall in Preston.
An extensive search was launched to find the mum-of-two, involving police, firefighters, mountain rescue, underwater teams and the local community.
Officers scoured wooded areas, ditches, water margins and the grounds of an abandoned house.
A specialist search was also launched by dive expert Peter Faulding, who used £50,000 sonar equipment to scour the water.
He later pulled out of the hunt, saying he did not believe Nicola was in the river as she could have "stood up" if she fell in.
Nicola's disappearance sparked a huge amount of speculation online with web sleuths flocking to the area she was last seen in an attempt to crack the case.
For her funeral last month a no fly zone was put in place over the church - so sick TikTok sleuths couldn’t film her funeral using drones.
The move comes after a sleuth was arrested for filming and uploading footage of Nicola’s body being recovered from the River.
