The incident took place in Miguel Couto Municipal Hospital, a public hospital in Rio de Janeiro on Monday.
The video shows him wandering around in the corridor with his body contorted either in pain or perhaps, as news site CanalR1 claims, from the effects of drugs.
Off-camera another man can be heard chanting The Lord’s Prayer before saying to the victim, “You are not powerful, you are not powerful!”
“I am better than you, you are corrupted,” the victim responds before claiming that he is working with “Lucifer”, another name for the devil.
He also asks the man off camera to hit him and to kill him. “I will not hit you because God is greater,” the man responds.
The video has been widely shared since the incident took place with many people claiming that the man was possessed by the devil. “Just as there is God, there is also the devil. Never doubt that, the good and the evil is there enough and people choose,” Cifras Gospel wrote on Facebook.
