A second woman from Norfolk has been arrested by police investigating the murder of a woman in Cambridgeshire more than 30 years ago.

Sally McGrath disappeared in Peterborough in 1979 and her was body found in woodland the following year.

A 49-year-old woman from Great Yarmouth is being held on suspicion of assisting an offender and perverting the course of justice.

Police said a woman, 55, also of Great Yarmouth, has been bailed.

She was arrested on Wednesday on suspicion of the same offences.

The arrests come after police reopened the case along with inquiries into seven sexual offences.

Final sighting

Two men were arrested in connection with the murder on 3 December and later released on police bail.

A 58-year-old from Fareham, Hampshire, and a 53-year-old from Great Yarmouth in Norfolk were both held on suspicion of murder.

Miss McGrath, who was living with her parents in Tower Street, Peterborough, was last seen on the afternoon of 11 July 1979 at the Bull Hotel, Westgate, in the company of a man.

Her body was discovered partially buried in Wild Boar Spinney at Castor Hanglands in March 1980.

A post-mortem examination revealed she had died from a blow to her head, but it is not known what caused the injury.
