University officials said the victim entered a parking garage elevator where two other people were already. When she exited at the eighth floor, officials said one of the people in the elevator tried to take her phone out of her hand. She tried to hold onto her phone and the other person pushed her out of the elevator, officials said.
The two suspects remained in the elevator with her phone and it left the eighth floor, the security alert said.
Officials said the victim had a scraped knee and refused medical treatment. No weapon was shown or threatened.
