A Rangers flag featuring a Nazi SS symbol was displayed in the away end at Tynecastle this afternoon.
A banner draped from railings in the away allocation - during the 0-0 draw with Hearts - included imagery of a Totenkopf.
Rangers are aware of the matter and have condemned the display with an investigation already underway.
The skull and crossbones symbol - also known as the Death's Head - was used by Adolf Hitler's bodyguard unit during the Second World War.
It was particularly used by those guarding concentration camps and who committed a number of atrocities during WW2.
The insignia was also the symbol of the 3rd SS "Totenkopf" Panzer Division, responsible for several war crimes.
This included the 1940 Le Paradis Massacre, where 97 British soldiers from the Royal Norfolk Regiment were murdered after they surrendered.
The flag featured a Rangers badge, 936 the Totenkopf and the words "Expand or perish".
"No surrender" was written across the white cross on the blue flag.

The display was spotted at Tynecastle after Rangers officials condemned a similar flag seen at Ibrox last season.
In October, a flag with the Totenkopf branded 'Rangers Active Unit The Firm' had been slammed by club chiefs. An investigation was launched into the matter.
A Rangers statement reads: “We can confirm that we are aware of this matter.
"The club repeats its strong condemnation of the display of such imagery and confirms that an investigation is already underway.”
Hearts have been contacted for comment.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
