A VIDEO that appeared to show Rangers players singing sectarian songs was doctored to include bigoted language, police believe. 

The video went viral on social media and was investigated by Police Scotland.

It's now thought by cops that it was edited to include sectarian chants, reports the BBC. 

In May, Assistant Chief Constable Gary Ritchie said: "We're looking at that now to see if we can identify any individuals who are committing offences."

Humza Yousaf in his former role as Justice Secretary also commented on the video at the time, saying: "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 and determine the facts around it."

A statement from the club released that month said: "It is evident that this video was shared with an adjoining narrative which attempts to discredit our players and the reputation of Rangers Football Club.

"We are confident that no criminality took place, we have sought legal advice and look forward to cooperating with Police Scotland."

We told previously how Police Scotland confirmed they had established "no criminality" in their investigation into the video. 

Police Scotland was approached for further comment.
