San Francisco State University campus police have arrested a "person of interest" believed to be responsible for "an anonymous, non-specific threat" earlier Tuesday, but classrooms and campus buildings remain closed until Wednesday.

University Police announced Tuesday afternoon that it believed there were "no ongoing threats to the campus community" after a suspect was detained, and students living on campus were free to leave their buildings just before 1:45 p.m. Classes remained online for the rest of Tuesday.

San Francisco State University President Lynn Mahoney told reporters on Tuesday afternoon that the person detained wasn't affiliated with the school. Neither Mahoney nor campus police identified the suspect by name.

The school first notified students about a potential threat at 3:05 a.m., according to the Golden Gate Xpress.

Authorities told the student paper they were investigating a possible active shooter threat on campus, stemming from a post Monday night on the Instagram account "SFSU Confessions."

An anonymous user, under the handle @bsnsnsnsnsnnn000, posted, "armed on campus… see y'all tomorrow."

The comment was deleted shortly after.

"I'm, first of all, very grateful to our students who alerted us so quickly because the post was posted so briefly that we might not have caught it," Mahoney said Tuesday afternoon. "I'm also extremely grateful to our University Police Department and our emergency operations center, both of whom worked through the night to enable us to make the decision in an abundance of caution to work remotely today."

The start of in-person classes was originally delayed until 10 a.m. before the school announced just prior to 8:30 a.m. that all instruction and services the rest of the day should move remote if possible. In addition, students living in on-campus housing were asked to remain inside until the investigation concluded.
