POLICE divers searched a stretch of canal in the hunt for missing Burnley gran Susan Gray.

Her family's anguish is now stretching to a third week after frogmen failed to find any trace of the troubled mum of four, who disappeared from her Allerton Drive home on November 9.

Police chiefs stressed the canal was only searched as it is in an area where Mrs Gray was last believed to have been spotted.

But they admit there have been no new leads or sightings.

Mrs Gray, 55, is said to have suffered depression after her mother's death. She scribbled a note to her family saying: "Sorry, I can't let you see me like this any longer. I know I've got Alzheimer's," before leaving without her handbag, cash or medication.

There has been only one reported sighting, at 8.50am on Saturday, November 12, when a woman fitting her description was spotted wandering from the railway track towards the platform at Burnley Central Station. Divers from the underwater search unit spent five hours at a stretch of the Leeds and Liverpool Canal yesterday, close to Burnley Barracks, between Westgate and the M65.

Family members have put up posters in Burnley, Accrington, Blackburn, Preston and Blackpool. Distraught daughter Lisa, 22, said her mother's personality had changed from out-going to withdrawn. It is the second time she has gone missing but last time she returned safe after two days.

Susan lives in Burnley with husband Jimmy and daughter Kerry, 21.

She is 5ft 2ins tall, with collar-length dark brown, wavy hair and green eyes. She may be wearing glasses and was wearing trousers and a three quarter-length grey duffle coat and calf-length brown boots.
