A helicopter ambulance landed in Sainsburys’ supermarket’s car park last Thursday morning after a 70-year-old man was found with serious head injuries in the front path of a house in Dalston.

Mystery surrounds exactly how he came by his injuries, but London’s Air Ambulance says it was called to deal with someone who had “fallen from a height” in Dalston Lane.

The air ambulance was scrambled and two road ambulances and a car ambulance attended,

A spokeswoman from London’s Air Ambulance said: “The patient was stabilised at the scene before being conveyed in a road ambulance to the Royal London Hospital in Whitechapel.”
