A man found critically injured on Stansmore Road, Meir, had suffered an accidental fall, according to police.
The 40-year-old man, from the Stoke-on-Trent area, sustained a serious head injury and is currently in an “unstable and critical” condition in hospital after being found last night (February 18).
At first, police believed the man may have been attacked, but have now concluded it was an accident.
A Staffordshire Police spokeswoman said: “A 43-year-old man from the Stone area who was arrested on suspicion of wounding has been released without charge.
“Officers have concluded their inquiries and are not looking for anyone else in connection with the matter.”
Residents spoke of their shock at the incident.
Pete Brocklehurst, 40, said: “My 15-year-old son was home alone here at the time.
“The police didn’t leave the road until about 2am, after they blocked it off.
Linda Bauthwick, 68, said: “The police came and knocked on my door and I was worried that it was about my son.
“I saw the police and the ambulance arrive last night, too.”
Brian Horn, 71, said: “There were ambulances and the police had closed the road, they were still here when I went to bed at 11pm.
A spokesperson for West Midlands Ambulance Service said: “We attended the scene at Stansmore Road at 8.32pm last night following calls that a man had a medical emergency.
“We treated the man who was in his 40s at the scene, on the street and an ambulance took him to Royal Stoke University Hospital.”
