San Diego State University’s Love Library was evacuated Monday night after the university received a bomb threat, according to campus police.
Around 6:30 p.m. two notes were discovered in different men's bathrooms saying a bomb had been left on site, according to campus police.
SDSU officers swept the area, and six bomb sniffing dogs went through the 500,000 square foot building to check for any suspicious devices.
School officials reopened the library around 10:45 p.m. and have deemed it safe for students.
It is unclear at this time who left the notes, and why. Investigators said they will review security video and will take a close look at the notes to see if they are related.
