Hanover Police officers responded to an anonymous call Sunday night regarding an event at Gamma Delta Chi fraternity, director of Safety and Security Harry Kinne told The Dartmouth. The caller claimed that activities related to the organization's "Hell Night" were "putting people at risk," Kinne said. Hanover Police Chief Nicholas Giaccone contacted Kinne, requesting that College Safety and Security perform a walk-through of the house with the organization's president, Kevin Gallagher '11, Kinne said. No one in the house was at risk and the call was "not accurate," Kinne said. Gallagher declined to comment.
