A South Dakota State student was flown to a hospital in Sioux Falls after he was stabbed early Sunday morning in Brown Hall.

University authorities have identified Lucky Mai, a non-student, as the perpetrator. Mai remains in custody and a $75,000 cash-only bond.

The incident happened when the student entered an unlocked room in Brown Hall. Mai was in the room and a confrontation broke out between the two, which resulted in Mai stabbing the student, according to an email sent to the campus community from Don Challis, assistant vice president of Safety and Security.

Weapons of any kind, including shotguns, rifles, pistols, paintball guns, martial arts weapons and knives with blades longer than four inches are not allowed in the halls, according to university policy. University Police offers gun storage at no charge to students.

Counseling services are available and students are encouraged by Student Affairs officials to reach out.
