Exclusive Video Shows Group Beat Grandfather in Bronx

A group of men loitering outside a Bronx building were asked to leave because they were playing music and talking loudly. But a few members of the group didn’t like that, so they threatened the 62-year-old building super, and his teen grandson tried to intervene. The grandfather was punched after being knocked to the ground. NBC 4 New York’s Marc Santia reports.
