WESTFORD -- Police arrested an employee last night at Westford Academy who serves as custodian at the school.

Police Lt. Hervey Cote confirmed custodian Christopher Selway, 54, who lives in Concord, was taken into police custody at Westford Academy Tuesday evening for an alleged violation of a restraining order. Cote confirmed this incident did not occur on school grounds and Selway attended court on the issue Wednesday.

Principal James Antonelli sent an email out to parents notifying them of the circumstances the following morning, which he shared with The Sun Wednesday afternoon. In the email, Antonelli said the custodian has been a district employee for "many years."

"(He) has been a very good worker. This is a domestic issue and the custodian is not a safety issue at our school," Antonelli wrote. "Several students witnessed the employee being escorted by the WPD to a police vehicle in front of the school. I felt it was very important to provide you with an update in order to dispel any rumors."

Antonelli told The Sun regarding Selway's employment status with the school at this time, he is unable to comment on the matter "pending a police and internal investigation."
