The YouTube video shows a victim bound to a chair in plastic wrapping tape, completely covered except for his head. One captor writes the word "snitch" across his forehead. Then two youths put him in a headlock while one of them draws a "Hitler mustache" on his upper lip.
Police say the investigation began in March when they got complaint about a picture of the assault posted on the social networking Web site, Facebook.com.
The suspects face charges of third-degree assault, unlawful restraint and reckless endangerment.
