Investigation will not start except there is a complaint. CAF will look into the matter if the NFF make a formal complaint. As it stands now, CAF is not aware of this shameful incident. Morocco needs to be sanctioned for this disgraceful act. A fine or playing without fans for some matches might be a worthy punishment. For now, the Nigerian is in the mood of celebration, maybe they would have hastily sought justice if we had lost the trophy.
I don't blame them though, it's Fifa that doesn't invest too much in African leagues. If this happens in Europe, that person would have face life ban from coming to the field and I'm sure other people will learn from it and stop the act too. You no fit even try bring this kind thing comes field in other countries because you are going to be search, final matches are always tough to monitor and such tight security is always put in place but because it's us why it's happening.
They are lucky that we won by the way otherwise I Trust Nigerians, they will accept the defeat but they will make sure justice is served but since we win, I'm not sure if the management will do anything about it. It's their country, they are going to use it as an excuse to cover up. Don't be surprised if they don't even say anything. Similar thing happened in cote divore when our men went for final, they did not allow Nigeriana into the stadium and they were chanting to make Nigeria lose which eventually never favor us.
