Celtic fans have been lambasted following their behaviour at Dundee on Boxing Day.
Dens Park Stadium boss Jim Thomson has revealed that staff at the Scottish Premier League fixture felt unsafe due to the boisterous nature of one section of Hoops supporters.
"I have never seen anything like the behaviour of the Celtic fans in the 20 years that I have been running games at Dens Park. Our fans were abused, our stewards were abused and no doubt the police were abused," he said.
"My staff were genuinely at risk and it was not just a small minority to blame.
"I'm not pulling any punches here. I did not feel safe. It was like a throwback to the 1970s. It really was scary. I had Celtic fans coming up to me to tell me in the street they were embarrassed by their own fans' behaviour and the state they were in."
More than 70 Celtic supporters were ejected from the stands whilst fans urinated in the stands and fought with each other in what was a poor day for the Glasgow club despite winning 2-0 to go seven points clear at the top of the table.
