N ortheastern University’s undergraduate commencement at Fenway Park was briefly interrupted by a pro-Palestinian protest Sunday, as one graduating student was arrested by police after he left his seat and yelled at administrators early in the ceremony.

The students tell Boston 25 they’re facing 30-40 hours of community service and are still waiting for possible discipline from the school.

A week after police arrested nearly 100 protesters at Northeastern, the school held its commencement exercises Sunday at Fenway Park for the fourth consecutive year, and one person was detained during that ceremony.
