A shooting at Northern Arizona University killed one person and injured three others, the school said on Friday, adding that the suspect was in custody.
"Situation is stabilized," the university in Flagstaff, Arizona, said in a post on Twitter. The campus was not on lock-down, the university said.
The first call of shots fired came in at 1:20 a.m. local time, university spokeswoman Cindy Brown told CNN. The incident occurred in a parking lot adjacent to a residence hall, Brown said.
The three injured victims were being treated at Flagstaff Medical Center, Brown said. Their conditions were not known, she said. Brown said she did not know the identities of the victims or shooter, or if they are students.
