Portland (ME) Police are investigating an incident that took place late Monday night into Tuesday morning where people allegedly attacked officers with fireworks.

Portland police spokesperson David Singer said in a press release Tuesday that an estimated 300 people gathered around Kennedy Park around 9 p.m. where officers were targeted and shot at with fireworks when they tried to break up the crowd, News Center Maine reports.

According to Singer, multiple officers were checked after the incident. Some reported headaches and ringing in their ears from being close to the explosions for an extended period of time. No serious injuries were reported.

“Such unruly and dangerous aggression and use of force against our officers and community cannot and will not be tolerated,” Chief Frank Clark said.

A 17-year-old from Portland was arrested and charged with disorderly conduct and criminal use of explosives, Singer said.
