HUMBERSIDE and Cambridgeshire chief constables came under fierce attack today for their part in letting Soham killer Ian Huntley slip through the net.

Sir Michael Bichard is expected to pull no punches and to single out individuals for criticism when his report into the flawed handling of Huntley is published later.

The two police forces were bracing themselves for heavy criticism after Huntley passed police vetting checks to work at Soham Village College, despite a murky past.

It was from there he murdered 10-year-olds Holly Wells and Jessica Chapman in August 2002.

Sir Michael investigated how flaws in police intelligence handling and employment vetting checks led to Huntley being cleared to work as a school caretaker.

One source said: "The report gets straight to the point and Sir Michael is very plain talking."

The former Whitehall mandarin is likely to attack Cambridgeshire police for errors in vetting Huntley, while Humberside Police will also almost certainly be criticised for deleting records of his past.

It was only after his conviction last year that it emerged Huntley had been at the centre of nine previous sex allegations while living in Grimsby in the 1990s.

There were four suspected rapes and an indecent assault and four alleged incidents of underage sex.
