Four Americans have been charged for beating a mentally disabled man and showing it live on the internet.
Police in Chicago say the African-Americans tied up the 18-year-old white victim, beat him, cut his hair until his scalp bled, and forced him to drink from a toilet. It is being described as despicable, sickening and a hate crime.
The video also shows youths shouting obscenities against white people and President-elect Donald Trump.
The teenager's ordeal was broadcast live on Facebook, then went viral before the video was removed.
Should the internet and social media be policed?
