Boston Police report  a gun-toting man refused entry into the Lilla G. Frederick Middle School on Columbia Road  by officers Monday afternoon snuck back in to continue a beef with somebody at basketball tryouts there.
On seeing officers again, this time outside the school gym around 3:45 p.m., the man and three accomplices tried running away, police say. Officers caught one of them, but the man and two others escaped - at least until officers on patrol on Devon Street noticed two guys matching a broadcast description from the school:
Officers noted that one of the suspects was carrying a backpack. However, as officers approached, officers observed the suspect place the backpack on the ground, walk a short distance and then stop. Officers immediately ordered both suspects to the ground. A search of the backpack enabled officers to see and seize a firearm. Officers subsequently arrested the suspect, Dashaun Harris, 22, of Dorchester, and charged him with the Unlawful Possession of a Firearm.
The teen, Kwame Browder, 17, of Dorchester, was charged with trespassing, assault and battery on a police officer and resisting arrest.
