Police are still questioning a driver whose car hit five people outside a car wash in south London.
A 25-year-old man remains in a critical condition after the Mercedes mounted the pavement and ploughed into the group in Bellingham, south-east London, on Sunday morning.
Another 25-year-old man and a woman of 35 are in a serious but stable condition, while two other men aged 36 and 46 escaped with minor injuries. The driver was detained at the scene by an off-duty policeman.
He was treated in hospital for a head injury but has been discharged and is being questioned by police on suspicion of drink-driving and causing serious injury by dangerous driving.
Scotland Yard has confirmed the incident was not terror-related.
The crash happened opposite a row of shops in Bromley Road. The Mercedes careered through a row of bollards before hitting a low wall at the end of a hedge.
