Naked man 'high on drugs' cuts off his genitals and goes berserk in Chicago

Footage has been released showing a naked man yelling at people in a Chicago neighbourhood covered in blood after cutting off his penis, MailOnline reported.

The unknown man appears to be high on acid or synthetic drugs in the video clip filmed on Monday evening in the Irving Park community.

The footage begins by showing the man, who is bleeding profusely from his crotch, shouting nonsense and swearing at residents who are behind a large metal gate.

Witnesses can be heard screaming "calm down" before he charges toward a female Chicago Police Department officer who is standing in the middle of the intersection screaming "get outta here b****."

The officer quickly draws her taser as she yells at him to "get on the ground" before firing it at him.

The man, who appears to be in his 20s, falls to the ground.

The person filming the video can be heard shouting, "Oh my God, bro. Shoot his a**. Shoot that mother f****r. This is a time when you shoot people!."

Another police vehicle arrives to the scene and an officer gets out of the van. The man tries to stand up again and appears to charge the second officer, who tasered him once more.

The video clip ends with the man lying on the ground as he is surrounded by officers.

It is unclear if the man was arrested; his condition is unknown at this time.
