Police have arrested a man suspected of two different harassment charges, one up-skirt photo and an incident in a parking lot.

Officers with the Clackamas County Sheriff's Office arrested Artemio Trenado Trejo, 24, Wednesday on suspicion of unlawful entry into a motor vehicle and harassment.

According to a press release sent by the sheriff's office, a woman shopping at the Rite Aid in Wilsonville Tuesday caught Trejo "crouched down behind her taking a picture with his cellular phone camera up her skirt." Store employees detained Trejo until Wilsonville police showed up and arrested him.

Police determined Trejo was suspected of unlawful entry into a motor vehicle and harassment after a deputy recognized him from a May 3 incident. During that incident, a woman was in the Fred Meyer parking lot when Trejo began aggressively trying to talk to her.

"The woman made it very clear that she was not interested and got into her car telling him to stop and go away," the release read. "The woman's car window was partially open and he told her to unlock her door and then reached into the car even as she was driving away. She rolled her window onto his hand to cause him to remove the hand from the window."

Police came to Trejo's workplace Wednesday, a day after he had been released from the Clackamas County Jail.

Police are concerned there may be more victims and are asking anyone with information contact the non-emergency dispatch line at 503-655-8211.
