A total of four Morehouse College athletes have been arrested and charged in connection with two separate sexual assaults.

Report of the incidents – and the possibility that one involved the illicit party drug, “Molly” – cast a cloud over a prestigious college set to host President Barack Obama as its graduation speaker later this month.

Three of the students were charged in an alleged on-campus incident prior to spring break. The fourth was charged in a different case off campus that was reported in March.

According to Fulton County Jail records, Chukwudi Ndudikwa, Malcolm Jamal Frank, Tevin Mgbo and Lucien Kidd were arrested last month.

Ndudikwa, Frank and Mgbo, all members of the school’s basketball team, were each arrested on April 11 for the incident that happened on Morehouse’s campus, according to incident reports.
