MANCHESTER, Conn. (WTNH) — Police found a stolen gun on a high school student when they arrested him Monday in the Manchester High School parking lot, according to authorities.

The 16-year-old was taken into custody in connection to a “serious assault” that happened Friday night, according to police. When approached, the teen resisted arrest.

Police then discovered that he had loaded Glock 26 9mm gun that had been stolen out of Georgia in June.

The teen has been charged with first-degree assault, carrying a pistol without a permit, possessing a weapon on school grounds and second-degree reckless endangerment, among other charges.

Joseph Miceli, whose granddaughter attends the school, says change has to happen to prevent guns from being anywhere near schools.

“Something very positive has to take place,” he told News 8. “And they have to be held accountable for these actions a little more.”

The school district said it’s increasing police presence for the rest of the week. When students arrived Tuesday morning, two cruisers were parked in front of the high school.

“This kind of information provokes feelings of worry and concern, and I want you to know that we are working with police and community agencies to address these issues in a variety of ways,” Matt Geary, superintendent of schools, wrote in a letter to parents.

School officials also responded to another concern for parents: an uptick in fighting at Illing Middle School and Manchester High School.

Miceli said he hears about the fights from his grandfather.

“She says mainly the fights happen in the cafeteria, and I don’t think they know what to do,” he said.

Geary said the district would continue to respond to these issues with consequences for students, and additional fighting would not be tolerated.
