Police are appealing for a woman out walking her dog to come forward who may have seen car being abandoned near a cemetery after an alleged “hit and run” incident when an 11-year-old schoolboy was badly injured in London’s East End.

They want to speak to the woman who may have seen the car involved being left next top Tower Hamlets Cemetery Park not far from last Friday morning’s incident on the A13 Bow Road.

She could have “vital details” following the fail-to-stop collision, investigators believe.

Police were called to the incident near the pedestrian crossing on the corner of Alfred Street, opposite Bow Road Underground station, at 8.15am during Friday’s morning-rush-hour.

The schoolboy was taken by ambulance to the Royal London Hospital in Whitechapel where his injuries are described as critical.

The car, a silver-grey Audi A2, failed to stop—but was found by officers abandoned near the cemetery, Scotland Yard later confirmed.

The woman police want to talk to who was out walking her large black dog was wearing a blue or green jacket and may have seen the car being parked.

Witnesses or anyone with information about last Friday morning’s incident in Bow Road are being urged to call investigators from the Met’s Roads and Transport Command on 020-8597 4874, or anonymously call Crimestoppers on 0800-555111.

A 25-year-old man arrested in connection with the investigation “on suspicion of dangerous driving” and failing to stop has been bailed to a date in March.
