The Boston Police Department reports arresting a 17-year-old they say was toting a gun he'd just fired near Dorchester High School Tuesday night.

Police say that around 7 p.m., officers watching the Pop Warner practices at Dorchester Education Complex responded to a report of shots fired near Wentworth Street. "While responding to the call, officers observed a young black male running away from the scene in the direction of the high school. When the suspect refused to stop, officers began pursuing the suspect on foot. While pursuing the suspect on foot, officers followed the suspect as the suspect cut across the school football field (Roberts Field) and, in doing so, interrupted the Pop Warner practice."

Police say officers caught up with Michael Brown, 17, in a yard on Armandine Street. After retracing his steps and finding a gun in a pile of leaves, police say, the officers charged Brown with unlawful possession of a firearm, carrying a loaded firearm, unlawful possession of ammunition, discharging a firearm within 500 feet of a dwelling and disturbing the peace.
