A man is in custody after alleged threats of a mass shooting at the University of Alaska Anchorage.

Sunday morning around 10 a.m., police were contacted by a UAA student who said she'd received threatening text messages from a former boyfriend.

Twenty-one-year-old Ralph Marcelo - confirmed by police to be a former UAA student - reportedly sent several text messages containing suicidal threats that "quickly evolved into threats of a mass shooting on UAA campus," according to a release from APD.

The department notified UAA’s Incident Management Team about the threats, APD said, and officers also went to Marcelo's home to make contact. He was taken into custody without incident.

Marcelo was remanded at the Anchorage Jail on charges of Terroristic Threats II, a Class C Felony.

APD said it takes these types of situations very seriously, and is "grateful to the student who immediately contacted authorities after receiving the texts."
