This video shows Maduro's national police (PNB), beating an autistic man in Lecherias, Venezuela. The man's name is Gianni Scovino, he's badly hurt, under arrest. If I get additional information I'll write updates below. If you don't like violence, don't watch it.
Update: Scovino is still under arrest, I have confirmation the video is real, it is included in articles in several reputable newspapers.
