According to the Ebonyi Police PRO, Chris Anyanwu,
When the police went for him, he was waving the machete which he used to cut his father’s head and threatening to kill anybody that gets close to him. He was overpowered all the same. “He was seen eating the entire stub of the neck. So when you look at the exhibit, the head doesn’t have the neck even though he did the beheading from the base of the shoulder. You will not see the part of the body that is supposed to be the neck; he ate it up.
