Three children and a woman have been taken to hospital after a serious collision in a Sheffield city centre car park this afternoon.
One of the children was seriously injured in the crash at the Q-Park multi-storey car park in Durham Road, police have said, while the other children and woman sustained minor injuries.
South Yorkshire Police said emergency crews including an air ambulance were called to the car park near the University of Sheffield students' union at around 4.40pm.
It said the incident was not thought to be an act of terrorism.
It has been reported that the injuries were caused when a vehicle rolled into the woman and children, but police have not confirmed the nature of the crash or how many vehicles were involved.
The ages of those injured have not yet been disclosed either.
Clarkson Street was closed following the crash but has since reopened.
