Police are hunting a thug dad who launched a 'barbaric' attack on a bus passenger after the man had asked the father's kids to stop throwing sweets at him.
CCTV images released by West Midlands Police show the seven-minute assault which left the terrified victim temporarily blinded after his attacker sprayed him with pepper in front of the two children.
The 21-year-old victim had been travelling alone through Birmingham city centre on January 11 when the suspect and a woman got on the number 24 bus with their young children.
After the children started throwing sweets at him, the man asked the father whether he could tell them to stop.
The footage then shows the yob storming to the back of the bus where he punches the defenceless victim.
The one minute, 14 second long clip then shows the father also launch a series of knees and kicks to the face as his female partner joins in the attack.
The attacker, the woman and children then left the bus at a stop near the Green Man pub in the Harborne area of the city.
The victim, from Woodgate, Birmingham, was treated at hospital for a badly broken nose and other facial injuries.
Police are now appealing for witnesses to the assault, which took place as the bus passed along Birmingham's Broad Street entertainment complex.
PC Rob Harper, from West Midlands Police, said: "The man was minding his own business when he politely asked the group to stop throwing sweets at him - but that request prompted a barbaric, prolonged attack.
"The victim had something like pepper spray squirted in his face which rendered him defenceless as the blows rained down on him.
"At one stage the attacker stands on a seat to get a better kicking angle, whilst the woman he was with also occasionally joined in the assault. The victim was lucky to escape with only a broken nose as it could have been much worse.
"What makes this even more shocking is that they unleashed this attack in front of the two children they were travelling with.
"These are clear CCTV images of both the main offender and the woman with him - if you recognise them or think you've seen them please call us."
