A fire damaged a Cal Poly San Luis Obispo residence hall, causing a major evacuation.
A mattress caught on fire about 4 p.m. yesterday, in Sequoia Hall. More than 100 students were evacuated from the complex, but most students were allowed to return about an hour later. No one was hurt, but several students have been temporarily displaced due to the damage to the bulding.
The cause of the fire is under investigation.
