Minneapolis police say they responded to multiple calls of rowdy crowds and reports of property damage in Dinkytown this weekend.

A viewer living in the college neighborhood near the University of Minnesota sent in videos of people lighting off fireworks just after 1 a.m. Saturday near 5th Street and 13th Avenue.

Police say a 17-year-old boy was hurt when a firework exploded in his hand.

He was taken to the hospital to be treated for a non-life-threatening injury. Minneapolis police haven’t released any information on arrests related to the incidents.

This happened right after the University of Minnesota announced a new initiative called Dinkytown Safe Streets.

Over the next few weekends, police say they will have ramped up patrols in the area to help disperse any disruptive groups.
