Police have given the public a fresh update on the case of missing mum Nicola Bulley.

Ms Bulley has now been missing for 19 days after she vanished while out walking her dog on January 27.

Lancashire Police along with a number of other specialist teams spent days dredging the River Wyre in Lancashire, which is close to the last place she was seen after she dropped her two daughters at school.

Assistant Chief Constable Peter Lawson and Senior Investigating Officer Detective Superintendent Rebecca Smith led the conference that started at around 11.50am.

At a press conference six days after Nicola went missing police first said its ‘main working hypothesis’ was that the mortgage adviser fell in the river during a ‘10-minute window’ between 9.10am and 9.20am that day.

They said her disappearance was not being treated as suspicious.

Her body has still not been found and detectives extended the search for her to the sea on February 3, saying finding her there ‘becomes more of a possibility’.

It was previously reported that police were trying to speak to several people in connection to Ms Bulley’s disappearance.

Two suspicious men who were seen ‘hiding their faces’ close to where Nicola was last seen were also claimed to be of interest to police.

While a red van that had been seen in area around the time Ms Bulley vanished was also believed to have been linked to the case.

Nicola’s husband, Paul Ansell, has made a number of pleas to the public with anyone with information to come forward, while also saying he will continue the search until she is found.
