The most recent blaze was reported at 11:30 p.m. in a trash barrel in a dorm’s laundry room, according to Norton Fire Department Capt. Jason Robbins. Students from the dorm were temporarily displaced during the investigation and have since been able to return.
No injuries were reported in the latest blaze.
On Sunday morning, fires were set in second-and-third-floor bathrooms at the McIntire Residence Hall, prompting evacuations for approximately 100 students.
