University of Texas at San Antonio canceled some afternoon classes Monday after its North Side campus received what officials now say was a non-credible bomb threat. Starting around 1:30 p.m., UTSA issued a string of posts on social media platform X, formerly known as Twitter, explaining it had received a bomb threat on its main campus. Although officials said they don’t believe the threats are credible, UTSA police cleared the campus’ Main Building, Business Building and Flawn Science Building.
