Caught on video: Man police say invaded women's privacy in Gresham bathroom

A still image captured from cellphone video shot by a woman in a bar bathroom in Gresham on April 25.

A woman caught a man on cellphone video as police say he invaded her privacy in a single-use, unisex bathroom at a bar in Gresham.

Prosecutors say the man, Matthew Dziewiontkowski, followed people to the bathroom and tried to invade their privacy more than 15 times in one night.

Police say they're looking for more possible victims.

On Tuesday, KATU talked exclusively with the woman who shot the cellphone video.

She said the first time he walked in on her she thought it was an accident, but after she spoke with her friends at 2nd Street Bar in Gresham, she set a trap for him.

For now, a judge's order bans the man from the bar as he faces a criminal charge.

"So finally I just was like, I need to videotape this," said the woman KATU is calling "Shannon" after she requested we not reveal her real name.

She said Dziewiontkowski invaded the privacy of her and others on the night of 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 other girls before me."

Police said the door to the bathroom is faulty.

Shannon said it's tough to lock if you don't slam it just right.

"After a while we would slam the door and the door did lock and he still would try to push open the door," she said. "Every time a girl would go to the bathroom he would get up and go."

After a few hours of watching Dziewiontkowski, Shannon said she decided to set a trap.

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

In the footage, Shannon closes the bathroom door, leaving it unlocked as she waits about 30 seconds before Dziewiontkowski opens it.

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

"I'm sorry," Dziewiontkowski says.

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

"I need to pee," Dziewiontkowski says.

"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 then walks away.

After investigating the case, police arrested him Monday. He was booked and released from the Multnomah County Jail on his own recognizance.

In court Tuesday, Dziewiontkowski pleaded not guilty to a misdemeanor charge of invasion of privacy.

The prosecutor said the bar's surveillance video shows him following people to the bathroom 16 times in seven hours.

Dziewiontkowski told KATU he has no comment.

"I'm relieved," Shannon said regarding his arrest. "I'm glad that people realize it's not OK to be a creep."

Dziewiontkowski is due in court again on June 21.

The owner of 2nd Street Bar sent a KATU reporter a message via Facebook saying in part:

The bathroom door has never been faulty. It has always shut and locked correctly. As long as the person using the bathroom shuts the door all the way it locks. Just like any other door, if the door is not pulled all the way shut, the door will not lock.
