Officers were called just after 3.20pm to reports a number of pedestrians had been involved in the collision.

Police have launched a murder investigation as they hunt the driver, who failed to stop at the scene.

Five other casualties were reported but none are believed to be life-changing or life-threatening.

Those injured were two 15-year-old boys, a 13-year-old boy, a 16-year-old girl and a 53-year-old woman.

Police believe all the teenagers are pupils at Debden Park High School on Willingale Road, Loughton.

Officers are still trying to trace the vehicle, a silver Ford KA.

Detective Chief Inspector Rob Kirby of the Kent and Essex serious crime directorate said: "This has been a truly shocking incident and my deepest sympathies are with all those involved.

"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."

Father Sam Stuart said a mass will be held at St John's Church in Loughton tonight following the collision.

He wrote on Twitter: "We will be saying Mass tonight at 8pm, St John's Church Loughton, for the children of Debden Park High School after the horrific events this evening.

"Church will be open tomorrow for prayer, lighting candles and if anyone needs to talk."
