BATON ROUGE - LSU briefly evacuated a building housing its Department of Chemistry amid fears of a potentially dangerous chemical leak Monday afternoon.

The university alerted students and faculty around 3 p.m. that Choppin Hall was evacuated due to the apparent leak. The building was later deemed safe, and it returned to normal operations shortly before 4 p.m. 

Baton Rouge Fire investigators have since attributed the situation to a malfunctioning alarm.
