The alarm was raised on Tuesday evening following reports of a 'medical emergency' but paramedics said there was little that could be done to save the woman, West Midlands Ambulance Service said.
A spokesman for the ambulance service told MailOnline: 'We were called to reports of a medical emergency at a private address on Lynmouth Close at 10.25pm, two ambulances attended. On arrival we discovered one patient, a woman. Sadly, it quickly became apparent nothing could be done to save her and she was confirmed dead at the scene.'
Police were initially scrambled after receiving reports of a woman in cardiac arrest at a home in the street.
A police spokeswoman added: 'Sadly, the woman was pronounced dead at the scene. Two men, aged 30 and 32, and a woman, aged 23, all from Biddulph, have been arrested on suspicion of murder and remain in custody this morning.'
