A vicious thug appeared to stamp on a baby boy while ambushing his dad.
Horrifying CCTV footage shows the parents walking with a carry-cot containing the tot when a man emerges from the side and walks straight to the dad before unleashing a savage kick in his face.
The father, who was carrying the infant, is then grabbed in a headlock and eventually forced to drop the cot as he tries to shield the boy from the attack.
As the baby falls to the ground, the attacker appears to get his feet tangled, which appears to lead to him kicking and stamp on the child.
While the baby's frantic mother scoops up her child from the ground, the attacker continues to pummel her partner with his fists.
The grainy footage shows the sickening assault was carried out yards from a crowd of people including young children in Kemerovo, Russia.
