Six pedestrians were hurt when they were struck by a car during rush hour in a busy central London street.
The injured people were taken to hospital
Two people were seriously injured and another four needed hospital treatment after the accident in Regent Street on Friday evening.
A 31-year-old man was later arrested on suspicion of dangerous driving.
A 200-metre section of Regent Street was cordoned, and a vehicle that crashed into a shop could be seen on the pavement.
A police officer manning the cordon said the vehicle had been crossing Regent Street when it collided with a group of pedestrians.
"One person had his leg nearly torn off," he said. "He was in agony and was shouting."
Bill Kerns, who sells newspapers on the corner of Regent Street and Oxford Street, said about seven ambulances and three fire engines had attended.
