This is the horrific moment a father is caught on CCTV repeatedly STAMPING on a seven-year-old kid's HEAD. Amnat Salubthong, 43, was filmed running down the stairs of his apartment when he thought the other boy was bullying his six-year-old son. The footage shows the furious dad kick the lad in a red shirt away, then stamp on his head THREE times as he lays cowering on the ground. He then picks up his own son and delivers another savage kick at the shaking youngster before walking back up stairs to his apartment in Bangkok, Thailand. Amnat handed himself in to police after the clip was posted online and seen by cops who began investigating.
