A back-to-school event with over 300 attendees at Lewiston’s McGraw Park on Friday was interrupted by a teen male firing a gun into the air and ground, according to the Lewiston Police Department.

Lewiston Police say that they responded to a shots fired incident at McGraw Park shortly before 7 p.m. on Friday.

Maine Immigrant and Refugee Services (MEIRS), a Lewiston-based migrant advocacy nonprofit, was holding their third annual “Family Fun Day” back-to-school event in the park at the time.

Police said that when they arrived at the park it was filled with hundreds of people, mostly children, who were being given school supplies for the upcoming school year.

Witnesses told police that a teen male had “emerged and began to fire in the air and into the ground,” police said.

A vehicle was struck by the gunfire, but no one was injured in the shooting.

Police said that one female was treated at the scene for an asthma attack.

In a statement to social media on Saturday, MEIRS Executive Director Rilwan Osman said the Family Fun Day event was “aimed at bringing diverse parents and children together,” and prior to the shooting was “going wonderfully with over 300 attendees enjoying food, games, and activities.”

While the Lewiston Police Department’s statement indicates that the shooting occurred at the park, Osman claimed that the gunshots were heard “far from McGraw Park” where the event was being held, and that “no one who was attending our event was involved.”

“We’re disappointed that this joyful evening was disrupted, especially with so many families present,” Osman wrote.

“Maine Immigrant & Refugee Services is actively working with other organizations to provide awareness, education, and support to our youth and their parents in an effort to reduce gun violence in our community,” he wrote, thanking Lewiston Police for their “swift and professional response.”

About 15 minutes after responding to McGraw Park, Lewiston Police responded to another reported shots fired in the area of Pine and Horton Street.

Witnesses in the area told police that the shots “may have come from a vehicle or juveniles that were in the area.”

No injuries or damage were reported from the second shots fired incident, and investigations into both incidents remain active, police said.

This weekend’s shootings come as the latest in a string of shots fired incidents that have occurred in Lewiston this summer.

Just last week a juvenile male was injured in a drive-by shooting that occurred near the intersection of Pine and Jefferson Street in Lewiston, and a 17-year-old male who worked with MEIRS as a youth intern was killed in a shooting last month at a Lewiston public housing complex.
