A man entered an occupied community shower room in Apache-Santa Cruz Residence Hall, 1420 E. Fifth St., and approached a showering student at 10:10 p.m. Sunday, according to a press release issued by the University of Arizona Police Department.
The man walked through an unlocked door into the bathroom and confronted a female student who was showering, according to the release.
The man stared at the student and then entered an adjoining stall.
The student was able to run out of the bathroom and sought help from another resident who confronted the man and told him to leave, the press release stated.
The man disappeared from sight while the student was looking for a resident assistant.
The student told police the man was between 18 and 20 years old and about 5 feet 8 inches tall, weighing 150 pounds.
Police are hoping to find the man fitting the description, said Sgt. Eugene Mejia, UAPD spokesman.
"We want to talk to him and determine through speaking to him what his intentions were," Mejia said.
A similar string of incidents occurred in April 2002 when two male suspects watched people shower on six different occasions in residence halls.
One man was arrested that year, but three days after his arrest, another man attempted to sexually assault a student in a residence hall shower.
Police enacted a whistle program in which they handed out safety whistles on campus and put all residence halls on 24-hour lockdown.
