Three teenagers have been arrested over the death of a 27-year-old woman from Warwickshire.
Gemma Hayter's body was found by a jogger on a disused railway line in Rugby on Monday. Tests have failed to establish the cause of her death.
The teenagers, aged 17, 18 and 19, were arrested on suspicion of murder on Tuesday night.
A man, 19, and woman, 21, were arrested on Monday and remain in custody. A man, 35, arrested on Monday has been bailed.
All six were arrested on suspicion of murder.
Police have appealed for anyone who knew Ms Hayter, of Biart Place, Rugby, to come forward in the hope that this will yield more information about her final movements.
They also want to hear from anyone who was on the stretch of railway line, between Hillmorton Road and Pytchley Road, where the railway station used to be, between 1800 BST on Sunday and 0600 BST on Monday.
