This is a new one and I think it Originated in Ghana. I received the broadcast not to accept friend request from a certain Amos Lacat on the claim that the operator of the said Facebook account is a terror and a killer. 

I went further to verify by asking how true the source is but the reply came in to say .. “Can’t you see how scary the face is?” Lol

Anyways until it is verified, stay safe and stay careful.
