The president of Grand Valley State University says he feels "devastated" by four sexual assaults near campus and calls the recent series of attacks a "cancer."
Thomas Haas tells WOOD-TV that everyone must be vigilant and "really take care of each other."
The fourth assault of female Grand Valley students was reported Tuesday night outside off-campus apartments. The first occurred on Aug. 26.
Meanwhile, more than 100 people attended a public safety forum Thursday at the Allendale campus, including the president, students, faculty and police.
Grand Valley officials are urging students to check in with friends more frequently, participate in ride shares and walk in groups.
Police believe the attacks probably are connected, but they haven't made a definitive conclusion.
