Shortly after kick-off, a banner was displayed above the stadium reading: "White Lives Matter Burnley". "This, in no way, represents what Burnley Football Club stands for and we will work fully with the authorities to identify those responsible and issue lifetime bans".
In his submit-match interview with Sky Sports activities, Mee additional that he felt it was a "modest minority of persons" who have been not supportive of the Black Lives Make any difference motion.
A spokesperson from Paradigm Precision said on Wednesday: "We have concluded our investigation into the conduct of one of our employees in relation to an incident at the Burnley v Manchester City match, as well as other related manners. What a mad world we live in". I believe that it's also important to acknowledge that white lives matter too.
"It is to highlight that black people are being denied certain human rights simply by virtue of the colour of their skin".
"This crass publicity stunt was done with the intention of offending and causing hurt to so many in our community and those responsible should be ashamed of their desire to divide people", he said.
"The movement, the issues that are being discussed and the change that will arise is unstoppable".
