A student at a K–8 school in Jamaica Plain will be facing possible legal and disciplinary consequences after allegedly showing another student a weapon Friday morning, school officials said. In a message to parents sent at 4 p.m. Friday, Katie Grassa, the principal at the Curley K–8 School in Jamaica Plain, said it was an “upper grade” student who allegedly showed the weapon and that the school was “taking this incident very seriously.” “There was never a present danger to any student or staff at the Curley,” Grassa said in the message. It wasn’t immediately clear what type of weapon was involved in the incident. Boston police and Boston Public Schools police officers responded immediately to the incident, Grassa said. Calls and e-mails to the school and to the school district were not immediately returned. The school is in contact with the student’s family and the student is receiving “necessary intervention,” she said. The student will be subject to consequences from the legal system and disciplined in accordance with the BPS code of conduct, Grassa said. “Weapons of any kind are not allowed inside the Curley or in any Boston public school,” she said. No further information was immediately available. Breanne Kovatch can be reached at [email protected] Follow her on Twitter at @breannekovatch.
