Authorities made two arrests at a Boston playground on Wednesday, taking a 16-year-old into custody for charges of firearm possession and arresting his 25-year-old acquaintance for allegedly causing a scene during the incident.

Shortly before 6:00 p.m. on Wednesday, officers on patrol near a playground at the corner of San Juan and West Newton streets observed two men break away from a larger group that was congregating, police reported. The officers saw that one of the individuals kept grabbing at his waist, as if checking for a gun.

The officers exited their car and approached the men to speak with them, authorities added. During a routine pat frisk for safety, an officer felt that the 16-year-old had a firearm, and he was placed under arrest.

As officers made the arrest, the other man became belligerent, according to police. He was yelling at the officers and causing a large crowd to gather in the street.

After warning him several times to quit his disturbance, police took 25-year-old Mwase H. Potts of Boston in custody and charged him with disorderly conduct, officials added.
