This is the shocking moment a masked thug hurled a concrete slab through the window of a family home -- which left a 10-year-old with a gash to his FOREHEAD.

Year five pupil Lewis Buckley was hit with a shard of glass in what is thought to be a random attack.

Dramatic CCTV footage shows the assailant running up to the house before launching the missile, which shattered the living room window, at around 11.20pm on Saturday, August 4.
