At least 12 people have been injured, some seriously, after a series of "hit and run" accidents in Cardiff in which pedestrians were reportedly targeted by the driver of a white van.
Police have arrested a 31-year-old man following the crashes, which occurred at around five different locations in the Ely and Leckwith areas.
The casualties, who included children, were taken to the city's University Hospital of Wales.
The accident and emergency department was only dealing with those injured in the crashes, and it was closed to other admissions.
Police were at a number of locations including Crossways Road, Cowbridge Road West, Grand Avenue, and Sloper Road, and have advised motorists to avoid the areas.
A local trader claimed that he was told that the driver at the centre of the series of crashes targeted pedestrians deliberately.
Ramesh Patel, who runs RM Patel Convenience Stores on Cowbridge Road West, said: "I was in the shop working at the time so I didn't actually see anything but customers have said a white van purposely drove at people."
"Obviously, when someone tries to run you down deliberately that is frightening, not pleasant at all.
"I was working here in the store so I didn't see that myself but that is what most people who have come in here have said. People seem very shocked."
Another trader in nearby Grand Avenue said customers were shocked and panicked by what had happened.
"People are very upset and panicked by what has happened. They are very shocked," said Harbhajan Dhaliwal, who runs a general and convenience food store in the road.
"People coming in here are very, very shocked and panicked. It is actually quite quiet here now. Business is slower than usual because the road is closed after what has happened. This has also upset people."
The ages and conditions of those injured have not been confirmed.
