A man has been arrested on suspicion of murdering a 12-year-old boy who died in a hit-and-run outside a school.
The 51-year-old was also detained on suspicion of attempted murder after four other teenagers and a 23-year-old woman were also hurt in the crash.
It happened near Debden Park High School in Loughton, Essex, at about 15:20 GMT on Monday.
Essex Police said officers were looking for a silver Ford KA that was “likely to have damage to [its] front”.
Earlier, the force took the step of naming Terry Glover, 51, as someone they wanted to speak to in connection with the crash.
It is understood that all of the injured children – two 15-year-old boys, a 13-year-old boy, and a girl, 16 – are pupils at the school.
Debden Park’s head teacher Helen Gascoyne, said: “Our thoughts are with the family and all those affected.
“The school will be open [on Tuesday] with a number of counsellors on hand to support our community.”
‘Liked and loved’
Christian Cavanagh, executive head teacher, described the boy’s death as “a young life so tragically lost”.
He said: “This young man had made his mark on the school and was liked and loved by staff and students.
“We will consult with the family and our school community to decide how best to commemorate his life.”
Det Ch Insp Rob Kirby described the crash as “truly shocking” and appealed for dash-cam footage.
“I would like to thank the many members of the public who have called us with information and spoken to our officers, as well as those who provided crucial medical assistance at the scene,” he said.
The crash happened on Willingale Road, which cannot be accessed from junctions on either side of the school and remains cordoned off.
Police initially said the injured woman was 53.
