Police SWAT Summer Jam Violence

Police arrested 19 and said there were between 50 to 100 violent confrontations at the Jam’n 94.5 Summer Jam at the  in Mansfield, Mass., June 16.  

A large number of the assaults occurred outside the venue on the surrounding lawn, and WJAR-10 reported police had to call for backup from neighboring departments twice after finding the initial number of officers insufficient.

By the end of the concert SWAT vans and K-9 units were present, which police said was effective at discouraging festivalgoers from getting into further fights.

The Live Nation-owned venue’s manager, Jeff Mann, said during a meeting that the response from authorities was extreme and “made people really nervous as they were leaving the venue.”

The show featured performances from Fetty WapTy Dolla $ignKid InkFabolous and .
