Police searched the area around the building after the assault but did not find anyone.

Leong said the Main College Complex building has security cameras and police will be reviewing those. Campus officials also believe someone may have seen the suspect because he was dressed in an unusual way.

The campus remains open, Leong said, but campus officials are increasing the police presence on campus to help the community cope with the incident.

Counseling is available to any student who needs help and a crisis team is available to help the victim, Leong said.
