Arson is suspected in several fires that were started on St. Catherine University’s St. Paul campus Jan. 17.

According to the university’s Twitter page, fires were extinguished in seven buildings and the “incidents included fires set to a chair and papers in a garbage can.” No one has been injured.

The affected buildings were the Butler Center for Sports and Fitness; Coeur de Catherine; Derham Hall, an administration building; Fontbonne Hall and Mendall Hall, classroom buildings; Our Lady of Victory Chapel and St. Mary Hall, a dormitory.

On its Twitter page, the university posted at 12:10 p.m. that “we are aware of fires on the St. Paul campus today and working on identifying the cause. If a fire alarm goes off [in] your building, immediately move to safety. There are no drills today.”

The university also asked students to call its public safety department if they “see anything” or have information about the fires.

The St. Paul Fire Department is investigating.
