A tweet mocking the Ibrox disaster has sparked fury on social media.
The account which posted the tweet is believed to belong to a Dundee United supporter.
The user’s Twitter header picture shows a group of people behind a tangerine and black Lochee Arabs flag.
The post, which appeared during last night’s League Cup clash with Rangers and St Johnstone read: “Ibrox is empty because their fans have had great difficulty using the stairs again…” It was accompanied by a newspaper front page from the time of the disaster.
Rangers fans reacted in fury with one fan tweeting it was “truly disgusting.”
On a supporters forum, fans posted the person’s employer and their phone number and encouraged others to complain to his bosses.
The post read: “I’ll be complaining to his employers tomorrow as have many others so far via email and I urge as many as possible to do the same.
“Too many people make these comments and get away with it. Make him pay with his job.”
Fans threatened to report the matter to Police Scotland, but the Evening Telegraph understands the force has yet to receive a formal complaint regarding the matter.
In 1971, 66 people were killed in a crush when leaving the Old Firm derby.
