A teaching staff member at the Henderson Upper School on Croftland Avenue was taken to the hospital for evaluation after a student allegedly assaulted the staffer on Tuesday morning.

Boston Public Schools (BPS) said in a letter to parents on Tuesday afternoon that a “student engaged in a physical assault of a staff member” and several students witnessed it. The staff member sustained injuries from the assault and was seen by the school nurse and then taken to the hospital for further evaluation.

School staff and BPS Safety Services assisted in de-escalating the incident and are working with Boston Police on an investigation.

“The student involved will face disciplinary action in accordance with the BPS Code of Conduct, additional disciplinary action from law enforcement is also possible,” read the letter.
