NEWTON, Mass. – Boston College officials met behind closed doors with investigators most of the day Sunday as rumors swirled around campus about possible illegal gambling activity involving members of the school’s football team.

Boston College athletic director Chet Gladchuk had announced Saturday night that the school had started an investigation and asked for the Middlesex District Attorney’s assistance.

The university issued a statement Sunday night saying it was cooperating with the district attorney’s office and also setting up an internal review committee, headed by Kevin P. Duffy, vice president for student affairs. The statement said the university also had notified the NCAA of its actions.
