Hours after the evacuation of Southwestern College's Chula Vista campus and all centers Thursday, officials said they made contact with the person of interest involved and determined there was no threat.
The Southwestern College Police Department (SWCPD) launched an investigation just before 10 a.m. for what they considered a credible threat.
A spokesperson for the college told NBC 7 a student overheard another student make a threat during a math class. The student alerted their parent who in turn alerted the school.
"In an abundance of caution while we investigate, the college is canceling all classes and evacuating all campuses," said Southwestern College Superintendent & President Dr. Kindred Murillo.
Southwestern's main campus on Otay Lakes Road and three satellite campuses in National City, Otay Ranch and San Ysidro, plus their Crown Cove Aquatic Center on Silver Strand were all evacuated.
The Chula Vista Police Department assisted with evacuations, which the department called precautionary.

By 11 a.m., evacuations at the Chula Vista campus had concluded and CVPD cleared the scene as SWCPD continued their sweep of the empty school.
CVPD said it was safe to return to the area but the campus would remain closed for much of the day.
Just before 3 p.m., officials said the college would resume classes and normal business operations at all campuses on Friday.
Students or employees who needed to retrieve vehicles could enter through the H Street entrance, officials said.
Southwestern College's main campus and three satellite campuses combined serve about 20,000 students.
Southwestern College will evacuate the Chula Vista campus & all its centers Thursday, Sept. 6, while Campus Police investigate a credible threat. All classes are cancelled for the remainder of the day and all campuses will close. We will send updates as they become available.
