A man has been charged after he was caught on a cell phone camera invading a woman’s privacy, purposely walking in on her while she was using a single-use, unisex bathroom at 2nd Street Bar in Gresham, Oregon.

One of the victims, a woman, who wished to remain anonymous and be referred to as Shannon, told KATU that Matthew Dziewiontkowski walked in on her and some of her friends who were at the same bar on April 25.

“A couple of my girlfriends kept going or went to the bathroom and she told me that this guy walked in on her,” Shannon said. “Before that I went to the bathroom and he walked in on me. I apologized to him because I didn’t know that he walked in [on] other girls before me.”

“So finally I just was like, I need to videotape this,” she added.

Investigators said that the bathroom had a damaged door.

“After a while we would slam the door and the door did lock and he still would try to push open the door,” Shannon said, according to KATU. “Every time a girl would go to the bathroom he would get up and go.”

Shannon went on to describe how she executed her plan to catch Dziewiontkowski spying on her. She said she initially waited for only 30 second before Dziewiontkowski walked in on her.

“I coughed when I was taking the video,” she said, “so he heard me going to the bathroom.”

“Are you trying to [expletive] see me in the bathroom?!” Shannon shouts at Dziewiontkowski. “Every time I go to the bathroom you come to the door, every single time. I got you on film.”

“I’m sorry,” Dziewiontkowski responds.

“Are you being a [expletive] creep?” Shannon asks.

Dziewiontkowski replies, “I need to pee.”

“No,” Shannon says. “Then if the [expletive] door’s closed, go to the other door! … “I’m gonna call the [expletive] cops on you, you [expletive] creep!”

Dziewiontkowski is then seen walking away.

Dziewiontkoski was arrested Monday on a charge of invasion of privacy and is being held behind bars on $2,500 bail. He was subsequently released from the Multnomah County Jail. On Tuesday, he pleaded not guilty to a misdemeanor charge of invasion of privacy.

Prosecutors said Dziewiontkowski repeatedly followed people into the bathroom in an attempt to invade their privacy 16 times in seven hours.

Shannon said she is “relieved” that Dziewiontkowski was arrested. “I’m glad that people realize it’s not OK to be a creep.”

Dziewiontkowski’s next court date is set for June 21.
