A 12-year-old boy killed in a crash outside of an Essex school has been named locally as Harley Watson.
A man has been arrested on suspicion of murder after the boy and five others were hit by a car outside a school on Monday.
The 51-year-old man, from Loughton, Essex, was also held on suspicion of six counts of attempted murder and one of causing death by dangerous driving, said police.
In addition, he faces six offences of causing serious injury by driving, failing to stop at the scene of a collision and driving without insurance.
The arrest came after Essex Police earlier announced they were searching for Loughton man Terry Glover over the incident.
Two 15-year-old boys, a 13-year-old boy, a 16-year-old girl, who were thought to be pupils at Debden Park High School in Loughton, and a 23-year-old woman were also injured when the car ploughed into them.
Officers had begun a manhunt as they tried to trace a silver Ford Ka, with the registration LS08 OKW, which is believed to have been damaged in the crash in Willingale Road.
Head teacher Helen Gascoyne said the school had been "devastated" by the death of one of its students and that pupils would be offered counselling on Tuesday.
Chief superintendent Tracey Harman said on Monday: "We believe that the collision was deliberate and as such we have launched a murder investigation.
"We are investigating whether or not this incident may have been connected with another incident nearby."
Earlier, Ms Harman said searches had been carried out to try to locate Glover, as she appealed directly to him to come forward.
Police were called to the scene shortly after the end of the school day, at about 3.20pm on Monday.
East of England Ambulance Service sent 15 ambulances and 10 other vehicles, while three air ambulances were mobilised. The 12-year-old boy was taken to hospital where he died.
Essex Police said that the four teenagers and 23-year-old woman were treated at the scene or in hospital, and their injuries were not believed to be life-changing or life-threatening.
Detective chief inspector Rob Kirby said: "This has been a truly shocking incident and my deepest sympathies are with all those involved.”
Debden Park is a mixed academy school for pupils aged 11 to 18, which specialises in the performing arts and received a rating of "outstanding" in its most recent Ofsted inspection, according to its prospectus.
