A third person has been arrested in connection with the unexplained death of a 24-year-old woman in Buckingham on Tuesday.
Police were called to a house in Addington Road, by paramedics shortly before 11pm after they attended a person having a medical episode.
The woman was taken to Milton Keynes General Hospital, where she was later pronounced dead.
The property is still cordoned off and one police officer remains at the scene where a single bunch of flowers has been placed.
A post mortem examination of the woman’s body is due to take place today (Thursday).
The third arrest, which took place last night (Wednesday) is that of an 18-year-old man from Whitfield, South Northamptonshire.
Two other men, aged 34 and 26, arrested in connection with the woman’s death remain in custody.
