PORTLAND, Ore. (KATU) — A 30-year-old woman is accused of biting two people and punching a security guard during a violent altercation at a Northwest Portland bar.

For the third time in recent months, Portland police have made an arrest at the River Pig Saloon. The latest incident happened on July 2, when police were contacted about a woman who had been detained by security at the bar.

According to court documents, a woman told officers she was dancing with friends when the suspect bumped into one of them and pulled her by the hair.

When the suspect, later identified as 30-year-old Kayla Wiebe, was confronted, she allegedly tried to pull another woman’s shirt down to expose her breasts.

Wiebe then allegedly pulled the woman to the ground and bit her in the face.

When security tried to detain Wiebe, she punched a security guard in the face and bit him on the hand, according to court documents.

Police say that after she was arrested, Wiebe allegedly kicked the patrol car door more than 100 times.

Wiebe pleaded not guilty at her arraignment Monday to two counts of assault, three counts of harassment, criminal mischief and disorderly conduct. She was released on her own recognizance and is due back in court July 24.

Court records show Wiebe was convicted in Washington County in 2024 of assaulting a public safety officer and criminal mischief. She was sentenced to probation.

Earlier this year, a woman sued River Pig, alleging inadequate security after she was stabbed at the bar last December.

Court records also show Wiebe was convicted in Yamhill County in 2022 of harassment and fourth-degree assault. She was sentenced to probation and one day in jail.

In 2020, Wiebe was convicted in Washington County of DUII and reckless endangerment. She was sentenced to probation, and her driver’s license was suspended for one year.
