WICHITA, Kan. (AP) — Officials at Wichita State University say they plan to increase evening police patrols after two recent on-campus robberies.

University spokesman Lou Heldman said Tuesday the school will have additional officers on campus between 7 p.m. and 3 a.m. Heldman said the school is not adding officers, but rather using officers from day shifts more during the evening.

Officials say police officers will be conducting more foot patrols, as well.

According to school police chief Sara Morris, a 19-year-old female student was robbed of her purse at knifepoint Monday in a campus parking lot. The student was not injured.
