Rangers fans' group Union Bears have posted an image of vandalism at Motherwell's Fir Park on social media.
Fireworks could be heard outside the ground as yesterday's match, which Rangers won 5-1, kicked-off behind closed doors and pictures on a Union Bears Twitter account would suggest they were the source of the pyrotechnics.
Fans have been told not to congregate outside football grounds during the Covid-19 shutdown in Scottish football.
However, a post on the Union Bears account entitled "Motherwell (A) 27/09/20" shows fans, wearing hoods with their backs turned away from the camera, holding flares outside Fir Park and one also showed graffiti on the wall outside the stadium's main entrance.

The post has racked up almost 2,000 likes, but fellow fans have hit out at their alleged actions on Twitter.
@Davidss1 posted: "UB defacing everywhere, as a born and raised bluenose I must say I hate this!"
@IainAllan3 said: "Well played in possibly delaying fans getting back to football. Legit beyond stupid doing things like this atm as while the cases rise incidents like this will be scrutinised and used as an example why fans aren't allowed back yet..."
And @Wallis819 commented: "This is a let down, immature folk, what are they trying to prove?"

Rangers won the match comfortably with doubles from James Tavernier and Cedric Itten, as well as a Jordan Jones strike, earning the three points for the Scottish Premiership leaders.
Motherwell have responded quickly to paint over the graffiti, although a faint outline still remains.
