Police at the University of California, Irvine were looking for a man who allegedly approached female students on campus and asked them if he could massage their feet and photograph them, authorities said on Thursday.

The first reported incident occurred on the afternoon of July 11 inside Langston Library. The man approached a student and asked her in Japanese if she could help him study for an English exam, a news release from UC Irvine police said.

After she agreed, the pair went to a study room at Ayala Science Library, at which time he tried to contact her “inappropriately,” according to the release. The female student felt uncomfortable and left.

Four days later, several female students said a man went up to them in the Student Center area, engaged them in conversation and then tried to get them to allow him to massage and photograph their feet, police said.

He took some pictures before leaving the area.

The “person of interest” was described by police as a 22-year-old Asian male, standing 5 feet 9 inches tall, weighing approximately 155 pounds and having dyed brown hair and brown eyes.

Police have not release a photo or sketch of the person they were looking for.

Anyone aware of other related incidents, or with information relevant to the investigation, was asked to call the UC Irvine Police Department at 949-824-3398.
