Nicola Bulley: Roads closed in search for missing mother

Nicola Bulley was last seen during a riverside walk on 27 January

Roads have been closed near to the area where missing mother Nicola Bulley disappeared three weeks ago.

Officers are at the scene in St Michael's on Wyre in Lancashire, where a police helicopter was also seen overhead and a tent has been put up.

A huge search operation was mounted after Ms Bulley went missing during a riverside dog walk on 27 January.

Police said they believed the 45-year-old had gone into the river and that her disappearance was not suspicious.

Police divers were seen working by the River Wyre

Det Supt Rebecca Smith, who is leading the investigation, has arrived at the scene outside the small village.

It is not known why the tent has been put up. There is a lot of police activity and journalists are being kept away from the area.

Divers were seen going into the River Wyre on Sunday afternoon about a mile from the bench where Ms Bulley's phone was found.

She was last seen walking her springer spaniel after dropping off her two daughters, aged six and nine, at school.

Her dog was found shortly after, along with the phone - still connected to a work conference call - by a steep riverbank.

The BBC has contacted Lancashire Police for a response.

A police helicopter hovered near the river for about 20 minutes
