Police investigating a hit-and-run incident in which a seven-year-old boy was critically injured have issued an e-fit of a man they wish to speak to.
The boy was crossing Leyswood Drive in Ilford, east London, on 28 July when he was struck by a van.
The van drove on for 20 yards while the boy was under the vehicle, police said.
It went on for a further 30 yards before the driver then stopped and walked toward the boy before driving off, police added.
The driver is described as white with blonde, spiky hair.
Det Insp Simon Sharp said: "We continue to appeal to this man to come forward. We would also urge anyone with information about him or the van to contact us as soon as possible."
The boy remains in hospital with life-threatening injuries.
