A student was in custody Monday in connection with a threat directed at Cal State Long Beach, which prompted officials to advise those on campus to shelter in place and others to stay away.
Campus police and university officials issued the alert about 3:45 p.m. after receiving what was described as a "credible threat," according to Jeff Bliss, the university's executive director of media and digital news.
School officials later said the threat was in an email that was shared with university officials about 2:10 p.m.
The female student, who had an appointment at a campus resource center, was located and taken into custody, officials said.
Campus police gave the all-clear at 4:23 p.m., reporting that shelter in place orders had been lifted and ``the sole suspect'' was in custody.
"There is no ongoing threat, and the campus is open for normal operations," according to a campus police tweet.
The lockdown of the campus was done out of an abundance of caution, Bliss said.
Campus police called it an isolated incident.
