An Arizona college student is dead, and three others have been arrested after attending an off-campus fraternity event last weekend. 

Officers were called to the scene at around 8:45 a.m. on Saturday, Jan. 31, after receiving reports of an 18-year-old male student of Northern Arizona University (NAU) who was "found unresponsive" at a house on South Pine Grove Road in Flagstaff, the Flagstaff Police Department said life-saving measures on scene until paramedics arrived."

The student, whose identity has not been released at the time of this report, was subsequently pronounced dead at the scene, according to authorities.

Investigators later learned the student "attended a gathering at the residence the previous evening, identified as a ‘rush’ event for the Delta Tau Delta fraternity," where several individuals – including the deceased student – consumed alcohol, FPD said. 

The incident led to the arrest of three Delta Tau Delta fraternity members, according to police. 

Twenty-year-old students Carter Eslick, Riley Cass and Ryan Creech were each taken into custody and charged with hazing in connection with the student’s death, FPD said in the statement.

Hazing is defined, in part, as the "submission of members or prospective members to potentially dangerous or hazardous circumstances or activities" that may result in personal injury, Delta Tau Delta fraternity chapter has been suspended "to allow a full investigation to take place and prioritize student safety." 

"We want to be clear: The safety and well-being of our students remain our highest priorities. Violence, hazing or any other behavior that endangers others has no place at NAU," the university added.

In 2022, hazing was criminalized in Arizona under Jack’s Law, with offenders risking punishment of up to 3.75 years in prison, according to Fraternal Law. 

The FPD, Delta Tau Delta's national chapter and NAU did not immediately respond to Fox News Digital’s request for comment.
