An investigation is under way after fireworks were aimed towards home supporters at Dens Park on Wednesday night.
Fans say they felt unsafe during the SPFL premier league match between Dundee and Celtic after away supporters launched pyrotechnics towards home supporters in the South Enclosure.
Dundee suffered a Halloween nightmare on the pitch, losing 5-0 to Brendan Rogers’ Glasgow side and supporters were left feeling further aggrieved, with some accusing police and stewards of inaction and allowing the large travelling support to get away with holding banned items in the Kilmac Stadium.
It is an offence for anyone to enter a football ground with fireworks, flares or pyrotechnics of any type, yet no arrests were made during the game.
Police are investigating with specialist football unit officers in an attempt to identify those responsible.
Video evidence of fireworks landing in the South Enclosure has appeared online, with police clearly visible in the vicinity.
One Dundee fan, who asked not to be named, said: “Policing at Dens was an absolute shambles on Wednesday night, it was embarrassing.
“The Green Brigade (Celtic supporters group) and Celtic fans were letting off pyrotechnics at will.
“As far as I could see, no-one was arrested — it’s changed days from how games used to be policed.
“The referee should have stopped the game, the devices were being thrown towards Dundee fans from the Bob Shankly stand.
“It was glaringly obvious where the trouble was coming from and the police and stewards did not intervene at all.”
Footage of Celtic fans appearing to sing an anti-poppy chant at Dens Park has also surfaced online.
The clip surfaced on the Football Away Days Twitter account on Thursday morning – and claims to show Hoops fans shouting “‘stick your f*****g poppy up your a**e”.
The post stated: “Celtic fans at Dundee last night with a controversial song”.
A Dundee FC spokesman said: “The club share the concerns being expressed by the home supporters.
“A plan was put in place to deal with the large numbers of visiting supporters in conjunction with our security team and Police Scotland.
“Search protocols were in place but it’s conceded it is almost impossible to search all fans in a crowd of nearly 8000 entering the stadium and unfortunately a small number of items did get in and were discharged.
“The club will be reviewing CCTV footage and will pass on anything which can help with any investigations Police Scotland undertake.”
A spokesperson for Police Scotland said: “We are aware of a number of incidents at the Dundee v Celtic match at Dens Park on Wednesday October 31.
“While we can confirm that no arrests were made at the game or immediately afterwards, officers from the Football Co-ordination Unit for Scotland (FoCUS) are investigating the behaviour of supporters at the match, with a view to identifying those involved in criminal behaviour, and taking appropriate action in due course.”
Celtic have been approached for comment.
