Humza Yousaf has called on Rangers to sack any players or staff members who are found guilty of "anti-Catholic hatred" amid the title celebrations on Saturday.
Officers from Police Scotland have launched an investigation after clips circulated on social media of allegedly showing Gers staff celebrating following the game against Aberdeen on Saturday.
The clip appears to show the Light Blue players singing a sectarian line to the ' Sweet Caroline ' song by Neil Diamond in a conference suite inside Ibrox.
Audio alongside the footage hears one line substituted for chants of 'f**k the Pope ' as people sing and dance.
Cops are now probing the video and said in a statement: "We are aware of a video circulating on social media apparently showing Rangers players using sectarian language while celebrating on Saturday.
"We are assessing its contents and will liaise with the Crown Office and Procurator Fiscal Service as part of our enquiries."
Replying to the police tweet the Justice Secretary Humza Yousaf said: "I have also been made aware of this clip, if (and I stress if) this clip is genuine then any player or staff member found to be guilty of anti-Catholic hatred should be shown the door by the Club.
"It is right Police Scot investigate & determine the facts around it."
Footage was originally shared on TikTok but has not been shared on YouTube, Twitter and Facebook.
Thousands of fans defied Covid-19 warnings against large gatherings and massed in George Square to celebrate Rangers winning their first Scottish Premiership championship since 2011.
The square was strewn with hundreds of broken bottles, plastic bags and spent flares after flag-draped fans had been seen attacking each other and launching bollards and other missiles at riot police.
So far 28 people have been arrested.
Rangers Football Club has been contacted for comment.
