An 18-year-old Prospect Hill Academy student was arrested Wednesday after bringing a loaded gun to school, police said.

The arrested student and Cambridge resident, Jemi Pearson, was taken out of class and into custody, according to NBC-TV’S Mike Pescaro, who first reported the incident.

Police told the station that Pearson faces charges of carrying a loaded firearm without a license, carrying a firearm without a license, carrying a dangerous weapon on school grounds and possession of a firearm without an FID card.

According to Boston 25 News, police weren’t able to find “a serial number, manufacturer, make or model on the weapon that was seized” out of Pearson’s gym class – putting it into the category of increasingly common “ghost guns” that this month were named a priority of the White House, albeit because other gun reforms are politically impossible to achieve in America. The guns can be assembled from a kit in as little as 30 minutes, according to the Bureau of Alcohol, Tobacco, Firearms and Explosives.

There have been four gunfire incidents reported by police this year, three of which have taken place in The Port neighborhood. None have turned up any shooting victims, and none have taken place in schools.

The charter school is at 50 Essex St. in The Port neighborhood. It educates more than 1,100 students in pre-kindergarten through 12th grade, according to a Prospect Hill Academy website.
