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 no that whenever rivals points at the opposite players sometimes means something either is an expression of dislike or other reason but on this case I don't think it would be taking serious because somebody could easily defend themselves in saying another reason why pointing at them, perhaps this could have been given attention if that was the group stage because they might definitely meet again but on the contrary that was the finals because after that day it will be the end of the season and they would have to rest for months before another new league will start again so actually is not necessary to take action.
