Police at ECU now say the woman who was attacked inside a bathroom was raped.
The alleged rape happened on campus at the Austin building on Wednesday afternoon.
The police report says the incident happened inside room 119 A just before 2:00 p.m.
Some students say they were not notified about the incident until Thursday afternoon. But university officials say they sent out an alert about the incident within two hours after it was reported.
ECU spokesman John Durham says that initial alert was a pop-up alert, meaning you had to be logged onto an ECU computer to see it.
University officials say an alert to those with ECU e-mail went out Thursday afternoon at 5:30 p.m.
Durham says the university has six different ways of notifying students about incidents and campus police felt the pop up alert was the quickest way to get initial information to students.
The search for a suspect continues.
