WATCH: Man Who Abducted A Young Girl On Subway Caught And Beaten By Neighborhood Vigilantes

An unhinged man was arrested — and then let go — after a wild day where he was apparently videotaped abducting a young screaming girl from a Bronx subway train — and then beaten hours later on a Bronx sidewalk by vigilantes who viewed the viral clip, cops said.

Sonny Alloway, 48, was found by police inside a Bronx deli where he sought refuge from a vicious street assault by angry attackers who kicked and punched the outnumbered man as one of the crew videotaped the frenzy of fists and feet. One of the assailants is heard accusing Alloway of sexually assaulting the apparently underage girl 13 hours earlier aboard the train.
