Boston Police report the arrest of a student on charges he ditched a gun a couple blocks away from East Boston High School this morning.

Police report that Keon Harris, 20, will be charged with unlawful possession of a firearm after Boston School Police and BPD officers found a .22 caliber RG-14 revolver outside 169 Brooks St. around 9:20 a.m.

In an assembly today, school Headmaster Philip Brangiforte told students that he's ordered increased searches and use of metal detectors because of the incident, even though "we honestly believe this is the safest school in the city of Boston."

He told students the incident "did not happen inside East Boston High School."

He also urged students not to talk to any media about the incident, because their parents would not know they were doing so - although he added that he ultimately could not tell the students what to do.
