Mt. Ararat High School has canceled two boys hockey practices and postponed Wednesday’s home game against Gorham in the wake of an investigation into an alleged bullying incident.

Heidi O’Leary, the superintendent for the Mt. Ararat school district that’s based in Topsham, advised parents in a letter Monday that practices for the three-school co-operative team would be canceled on Monday and Tuesday to address a report “of a potential bullying/harassment issue,” and to begin “an investigation in line with our district policies and procedures.”

O’Leary wrote in an email to the Press Herald on Wednesday that Lewiston law firm Brann & Isaacson is handling the investigation.

Lisbon and Morse high schools are part of the Mt. Ararat co-op.

The news comes after Lisbon forfeited the final four games of its high school football season this fall as the result of a school investigation into alleged hazing, though investigators later said no criminal wrongdoing had occurred.

Responding to specific questions, O’Leary wrote in an email that Wednesday’s home game in Watson Arena at Bowdoin College has been postponed. In her letter Monday to parents, she said that game could be canceled “depending on the progress of the investigation.”

O’Leary said she was notified of the bullying and harassment allegations late Saturday night. She did not answer questions about who made the allegations or who brought them to her attention.

Lisbon’s football hazing situation led to investigations by the Lisbon Police Department, the Androscoggin County District Attorney’s Office and Drummond Woodsum of Portland, a private law firm hired by the school department.

District Attorney Neil McLean chose to not bring any charges in that case, noting in his explanation that there are no state statutes regarding hazing and his office’s investigation did not reveal criminal activity. However, Drummond Woodsum’s report determined there was a “culture of hazing” within the Lisbon football team.

Asked if it was disappointing to learn of an alleged bullying incident barely three months after neighboring Lisbon forfeited the second half of its football season, Superintendent O’Leary wrote, “Of course it is disappointing to get this news, but I can’t draw any conclusions until the investigation is complete.”

The co-operative team competes in Class B South and is currently 3-3. They finished 1-16-1 last season.
