Police officers stand next to a person with a bandaged ankle near the Natural History Museum, after a auto mounted the pavement, in London, Britain October 7, 2017. "Enquiries to establish the circumstances and motive are underway", police said. "Thankfully there are no serious injuries with the majority now discharged from hospital", said Detective Constable Darren Case from the Met Police Roads and Transport Policing Command.
A 47-year-old man was arrested at the scene on suspicion of risky driving and taken to hospital for treatment, along with eight other people.
The arrested man was among nine people taken to hospital for treatment, police said.
The road is semi-pedestrianized and is usually busy with tourists, being situated between the Natural History Museum and London's Science Museum.
Police said it was a traffic incident after three attacks in the British capital this year in which vehicles were deliberately driven into people on the street.
London's Metropolitan Police said they were called to the scene at 2:21 pm (9.21pm Singapore time) after reports of a collision. Officers had arrested a man at the scene and he was now being questioned.

The BBC reports that Oliver Cheshire, the fiancé of local singer Pixie Lott, was among the members of the public who pinned down the auto driver after the incident. He said three female passengers in the auto told him it was a private-hire taxi.
Security is high in Britain after five terror attacks since March - four of them in London and one in Manchester - with the bloodshed claiming 35 lives. "Then the guy was screaming", he told the paper.
UK Prime Minister Theresa May was being updated on the incident, her office informed.
