SOUTH KINGSTOWN, R.I. — Police have arrested a 17-year-old boy who they believe threw a punch that caused brain trauma in a 39-year-old man during an altercation earlier this month in South Kingstown.

The teen, who wasn’t identified, was charged with felony assault in connection with the Aug. 12 incident.

Police say the victim and another 29-year-old man were assaulted after exchanging words with a group of young men walking along School Street after midnight. The teen charged allegedly landed the devastating blow on the victim.

Authorities say the boy is currently at the Rhode Island Training School while awaiting a hearing in Family Court. He’s reportedly well-known to police and has been criminally charged in the past.

The investigation is ongoing and more arrests are expected.
