This happened in Birmingham, where the CCTV cameras captured the moment this child was almost hit by a drain cover, that blew. Firemen arrived shortly after due to several calls complaining about the explosion, believing that it happened due to the build-up gas.
For the parents this must serve as a lesson. Next time they will pay more attention to the child that, actually, was walking in the street, not even in the sidewalk.
