The killer responsible for the murder of former Preston student PC Fiona Bone and her colleague PC Nicola Hughes has been moved to a secure hospital.
Dale Cregan is serving a whole life sentence for killing the officers and father and son David and Mark Short last year.
For four months Cregan was transported into Preston to stand trial at Preston Crown Court surrounded by a £6 million ring of steel in one of the largest security operations seen in the county.
Now Cregan has been transferred from HMP Manchester (Strangeways) to the maximum security Ashworth Hospital after refusing to eat for weeks.
Police sources say his behaviour has changed and he has “gone in the head.”
For four months he has been refusing to eat or speak to staff, spending 24 hours a day lying on his bed in the cell where he is segregated from other inmates.
Cregan went on the run following the murders of David and Mark Short last year.
On September 18 he lured PC Bone, 32, and PC Hughes, 23, to a house in Hattersley, Greater Manchester and killed them in cold blood in a gun and grenade attack.
PC Bone tried to draw her tasar but both officers died at the scene.
Cregan then drove at speed to Hyde police station and handed himself in.
Ashworth Hospital, near Maghull in Merseyside, is one of three maximum security hospitals in the UK and has housed Moors murderer Ian Brady since 1985.
