BBC pundits were urged to remain inside Celtic Park after full-time as AIK ultras congregated outside Parkhead following their 2-0 loss to the Hoops earlier this evening.

Swedish fans remained outside the stadium for a lengthy period of time before they were met by cops and stewards.

Beeb presenter Richard Gordon, who led coverage of the game inside the ground, explained to listeners and colleagues after the whistle that there was trouble brewing.

Celtic vs AIK: Fans 'throw punches' as stewards and cops wade into away stand

His fellow pundit Allan Preston reportedly warned his co-workers of the issues outside and told them to stay where they were.

"I'm getting warnings from Allan Preston who's outside telling us not to leave the stadium," said Gordon.

To which sports journalist Tom English replied: "Oh, why's that?"

Gordon explained: "Because there are ultras outside and massive police numbers."

The mass of fans would have come as no surprise as there were also incidents inside the stadium during the game.

We told earlier how punches were thrown by AIK fans who attempted to barge their way into the home support.

Eyewitnesses claimed to have seen supporters "boxing" stewards and officers as the fiery scenes got uglier.

Celtic won 2-0 thanks to goals from James Forrest and Odsonne Edouard.
