The UNM Police Department arrested student Kevin Boyar, 19, on charges of unlawfully carrying guns on campus Tuesday.
Chief Kathy Guimond said UNMPD received an anonymous tip that Boyar had guns in his room at the Student Residence Center.
No guns were recovered from Boyar's dorm, but Guimond said officers found evidence that weapons had been in the room.
Police then searched his parents' Albuquerque home and found guns and ammunition, she said.
Guimond said four guns were recovered from the house - an AK-47 style assault rifle, a 12-gauge shotgun, a 22-caliber rifle and a Russian bolt-action rifle with a bayonet.
Officers arrested Boyar on campus without incident, and he is being held at the department, Guimond said.
She said the investigation is in its preliminary stage, and charges are pending.
