UPDATE | A man suspected of harassing and in some cases even groping female students who volunteered to complete sexuality surveys for his class, has turned himself in to police, university officials confirmed Wednesday.

The suspect turned himself in to university police soon after officials sent out the email to the campus Monday evening, said Cal State Long Beach (CSULB) spokesman Jeff Bliss.

He is identified as 29-year-old Whittier resident Aaron Kosterlytzky, a CSULB graduate student in the social work program within the psychology department.

Kosterlytzky was cited for sexual battery and released on Monday. He was also issued a 14-day stay away order from the campus and is due in court in March 2018, Bliss said.

After university officials sent out an email Saturday based on reports Friday of the suspect’s actions, they received 14 to 15 more calls between December 9-11 by people who said they had been approached by him, had talked to him or had even been touched by him on their breasts or buttocks without their consent.

Police believe the suspect may be linked to similar cases reported since 2016.

PREVIOUSLY: CSULB Police Ask for Public’s Help in Identifying Sexual Harassment Suspect

12/13/17 at 2:59PM | Cal State Long Beach police are asking for the public’s help in identifying a man who allegedly harassed and groped female students on campus during surveys on sexuality he claimed were for a class.

The suspect, who identified himself as Aaron to the victims, is described as a Hispanic man in his twenties.

Authorities said the man would approach female students and ask them to complete a sexuality survey for his abnormal psychology class. The suspect would be cordial and inform the participants that the verbal question-and-answer survey was voluntary.

“As the survey progresses the questions become more sexual in nature leading the participants to feel uncomfortable and ultimately suspicious of the subject’s intent,” officials said.

The University Police Department (UPD) first alerted the campus of the incidents in an email sent out Saturday. Since then, officials said they received additional calls that the suspect reportedly engaged in physical contact, touching two females inappropriately.

“Two of the female subjects have reported that he touched their breasts,” officials said in an email to the campus on Monday.
