UPDATE: 4:27 PM One person was taken into custody around 3:30 p.m. Azusa Pacific announced about 4 p.m. that the lockdown at that college had been lifted.
Two school campuses were placed on lockdown Tuesday as police investigated reports of a shooting threat at Citrus College and the nearby Azusa Pacific campus in Glendora.
Details about the threat were not made immediately available.
Citrus College, which is located at 1000 W Foothill Blvd in Glendora, did not provide details on what prompted the lock down, only that students who are not on campus should "stay away" and that anyone still on campus should "go to the nearest room, turn off the lights, lock door and remain quiet."
According to KCAL 9, a telephone threat is what prompted the lockdown at Citrus College.
Azusa Pacific also tweeted an alert, asking students on campus to shelter in place.
"The Glendora Police Department is actively investigating a threat of a shooting directed towards Citrus Community College," the school said in a statement.
This is a breaking news update. More details will be added as they become available.
