Ten people are now known to have been injured after being hit by a car in a pedestrian area in central Dublin.
None of the injuries are thought to be life-threatening.
The car drove down Henry Street at around 1 p.m. Witnesses say it was travelling at around 40 m.p.h.
The driver of the blue saloon was arrested. He has been described as a non-national in his thirties. He is due in court tomorrow on charges relating to the incident. Earlier reports of a second man in the vehicle were denied by Gardaí who said that the man was travelling alone.
A Garda spokesman also said the car was not being pursued.
The car is reported to have entered the street from Moore street, although several witnesses have suggested it came from the direction of O'Connell street, and struck several people before crashing into barriers erected around an area where Dublin Corporation were working. The car then careered into a Corporation van.
"I just heard the noise of the car and he was speeding directly for us, so I had to decide to run. It took the barrier and a slab and pushed the van about five metres," said Mr Bob Alcorn of Dublin Corporation.
A witness who attended one of those struck by the car said one of the injured was a Spanish man.
"I heard people scream . . . I heard a bang and it blew them [people] all up in the air," the witness said. "It didn't deter him at all, he went tearing down the street." There were no signs of the car being involved in a car chase, she added.
A garda on patrol made the arrest and the man, thought to be in his 30s, was brought to Store Street Garda Station.
