The 15-year-old received a five-day suspension, and Mabry told WTNH she was never contacted by the school or the school district.
"I didn't receive a letter. I didn't receive a phone call,” Mabry told the television station. “I didn't receive anything from the nurse telling me my child was OK or if he was injured."
A school spokesman told WTNH that initial efforts to reach Mabry failed, but school officials eventually met with her.
In a statement, William Clark, the school’s CEO, called the incident “minor.”
“Police, security, school and emergency responders and nurse engaged,” Clark said. “The alleged victim was treated at school and did not require any further treatment."
