Attack by fan overshadows Hoops win
When Gary Hooper scored his second goal in the 49th minute — after Jambos midfielder David Obua had been sent off by referee Craig Thomson before the break for raising a hand to Charlie Mulgrew — a supporter came out of the main stand to grapple with the Parkhead boss.
An astonishing melee ensued and the intruder was eventually frogmarched up the tunnel by police but that was not the end of the trouble as some fans in the Celtic section of the ground appeared to fight with stewards and police.
