A man found injured in a street in Leeds is thought to have fallen out of a first floor window.
Emergency services were called to Roundhay Mount, between Chapeltown and Roundhay, at around 7.30pm on Sunday.
A number of police cars were reported on the street, along with paramedics.
The road was cordoned off while investigations were carried out.
A spokesman for West Yorkshire Police said initial inquiries suggested no-one else was involved in the incident.
“He is believed to have been leaning out of an upstairs window when he fell out,” the spokesman said.
Witnesses said officers were on the scene for several hours after the man, thought to be about 30 years old, was taken to hospital.
He remained in hospital for treatment today, although the extent of his injuries was not known.
