Butler University Police Department is looking into who was responsible for a theft in Lilly Hall on Monday night.

A wallet, a phone and an iPod were stolen from the costume shop of Lilly Hall sometime before 10 p.m.

Students were in the building, practicing for the theatre department’s “Bali Dream.”

When the cast was out of the room and upstairs doing quick changes, the items were taken from the costume shop in the basement.

In 11 weeks of police reports, 23 cases of theft from buildings have occurred. Nine have been reported in Lilly Hall.

In April, BUPD issued a warning to students after seven reports of theft were reported in 10 weeks.

No such warning has been issued this school year.
