After two persons died in Stoke-on-Trent, a 49-year-old lady was detained on suspicion of murder.
After 2 o’clock on Sunday, police were called to a car wash on Campbell Road in response to complaints of a man and a woman being assaulted.
The West Midlands Ambulance Service’s paramedics transported a man in his 40s to the hospital.
It is thought that his wounds are not life-threatening.
When police arrived at a house on Flax Street to make an arrest, they discovered two people there who were unconscious and hurt.
Despite the efforts of the paramedics, both of the unnamed victims passed away at the spot.
The woman is being held in detention after being detained on murder allegations.
The victims’ next of kin have been notified, and they are receiving care from officials with specialized training.
Detective Superintendent Nicki Addison, of Staffordshire Police, said: “This is a tragic case and we are working hard to understand more about what happened leading up to these two people losing their lives.
“We ask that people do not speculate on the circumstances at this stage as it is distressing for family and friends, and could hinder our enquiries.
“We understand that this incident may cause concern in the local community and further afield. We know that the woman arrested is related to the people and we don’t believe there is wider threat to the public at this time.
“Cordons are currently in place at a home on Flax Street and at a car wash on Campbell Road.”
The police are asking anyone with information that could aid in their investigation to contact them as soon as possible.
Detectives are especially interested in any dashcam or CCTV footage from the area of Flax Street and Campbell Road on Sunday between 1:30 and 2:30 pm, as well as any eyewitness accounts.
