The Scottish Professional Football League has opened a new investigation regarding an alleged illicit Celtic banner.
The Glasgow giants are already involved in an inquiry by UEFA relating to an obscene banner used during Tuesday night's Champions League loss to AC Milan but the SPFL are now looking into images and words used in last weekend's league clash with Aberdeen.
Banners displaying hunger striker Bobby Sands and Scottish Nationalist William Wallace with the accompanying words: 'The terrorirst or the dreamer, the savage or the brave, depends whose vote you're trying to catch, or whose face you're trying to save' were erected during the win over the Dons.
SPFL chief Neil Doncaster said the incident would be looked at more closely but fans group 'the Green Brigade' do not agree they have done anything wrong.
"The club's statement claims we assured them our display would be purely football related but that in fact it had nothing to do with football," read a statement.
"In reality however what was assured to them was that our plans were completely relative to Celtic and indeed football.
"Given that it is Celtic fans who are filling up prison cells and court rooms because of the Offensive Behaviour at Football Act, and the manner in which it criminalises legitimate expression of political opinion, this display could not have been more relevant in the current context.
"The fans are the lifeblood of any football club and to deem fan issues as irrelevant is frankly disgraceful."
