School officials in Haverhill and Methuen have taken disciplinary action against students who were involved in a major brawl that erupted after a Haverhill-Methuen basketball game earlier this month. “Both school systems have taken appropriate disciplinary actions,” Haverhill Superintendent James F. Scully said of the Feb. 19 fight at Haverhill High School, which involved some 200 students and resulted in seven arrests. Added Methuen Superintendent Judith Scannell: “We did a thorough investigation; In line with our school handbook and school policy, we issued appropriate disciplinary measures.” Neither Scully nor Scannell would elaborate or name any students who had been disciplined, citing federal privacy laws. According to Haverhill police, help from State Police was needed to break up the students when fights broke out shortly after 9 p.m., after Haverhill’s 65-58 victory. Students at both high schools reportedly had been exchanging warnings and threats via Twitter in the days leading up to the game.
