Four students – two men and two women – died after attending a post‑exam party in the town of Nsukka, according to police and university officials.

The University of Nigeria Nsukka announced three days of mourning, suspending academic and social activities while it works with security agencies to determine the cause of death.

Vice‑Chancellor Professor Simon Ortuanya said the university received a distress call at 22:00 on Wednesday and dispatched security to the house party at Praise Lodge, located in the Hilltop area outside campus.

Preliminary findings point to possible alcohol abuse or drug‑related paraphernalia, though officials stressed that conclusions have not yet been reached.

Police have recovered alcoholic drinks from the scene and taken the bodies for autopsy, while the investigation runs alongside a broader crackdown on unsafe alcoholic beverages in Nigeria.

In response, the vice‑chancellor announced a ban on signing‑out celebrations, a tradition where final‑year students mark graduation with parties, shirt‑signing and dancing.

He urged students to view graduation as a period for reflection and preparation for life beyond university, emphasizing communal mourning with families of the deceased.

The incident follows recent incidents in Nigeria where contaminated locally made alcoholic drinks caused dozens of illnesses and deaths, prompting the food and drug regulator NAFDAC to intensify raids on producers of fake or adulterated beverages.
