Updated with info that one of the suspects is not a kid.
Boston Police report arresting a 23-year-old man and two teens on arson charges for a May 23 fire that destroyed most of the playground equipment at the Sumner School on Basile Street in Roslindale.
Two of the three - a 14-year-old boy and a 16-year-old, both from Roslindale - had their arraignments scheduled for June 17, the Suffolk County District Attorney's office reports. Paperwork for the adult suspect has yet to be filed with the court; Boston Police declined to identify him.
Police did not say whether they are also the same three suspects spotted near the playground after a smaller fire the month before.
Parents and school employees are raising funds to replace the destroyed equipment.
