NJ State Police fire tear gas into angry Summer Jam concert crowd

The Asbury Park Press reports:

Witnesses say the disturbance began around 7 p.m. due to an altercation between concertgoers. That's when officials shut the gates to the show, the Hot 97 Summer Jam at the MetLife Stadium in East Rutherford, causing a logjam of people at the MetLife gate, which in turn led to metal barriers being toppled and thrown.

After concertgoers began throwing bottles in response, police then took up a defensive V-shaped position in front of the stadium gates as a barrage of bottles pelted the officers.
