The child was walking hand-in-hand with his parents just yards from their home on an inland council estate.
The flare, normally used by ships, coastguards and the military, was fired horizontally into the street from some distance away.
It narrowly missed the boy’s two-year-old sister, who was in a pushchair, before hitting him in the back, causing severe internal injuries.
A woman driving past the incident in Romford, Essex, stopped to administer
first aid before paramedics arrived.
