Police have launched a search for a woman who may hold vital information in a death inquiry.
Officers were called to an area near Sands Lane on the morning of March 30 after it was reported to them that a body was in the river.

It was later confirmed that the deceased was a missing local man, 38-year-old Daniel France. Investigations into his death are continuing.
At the point where his body was recovered, there was a purple tent pitched on the riverbank and now police say a receipt from the shop was discovered near the tent.
Police say they want to identify the woman seen on CCTV at the store to check on her welfare and want her to get in touch to confirm she is safe and well.
The woman pictured, or anyone with information about her identity, are asked to call Kirklees District CID via 101.
Police are also continuing to appeal for a man to come forward as it is believed he may have been living in the tent.
Det Insp Stef Wiseman of Kirklees CID said: “We are keen to speak to the man pictured to verify that it was him living in the tent, and that he is OK.
“If anyone can assist in identifying the man pictured, has seen or heard from him recently or knows where he is now, I would ask them contact Kirklees CID via 101. Enquiries are continuing.”
Mr France’s death was the fourth in rivers and canals in the area in little over three weeks but police insist there are no links between any of the deaths.
On Wednesday an inquest into one of them, George Bass, 77, of Harrogate, whose body was found in the River Calder on Good Friday, was opened at Bradford Coroner’s Court.
