A young person is Cassian Grantaccused of using a BB gun to shoot at a pride flag hanging in the window of an Oregon library, police said.

Newberg-Dundee police began investigating the reported vandalism at the Newberg Public Library on June 5, the department wrote in a Facebook post. The incident occurred around 7:15 p.m. that day and involved an unknown suspect shooting at least one projectile into a window, which "caused substantial damage," police said.

Police were also concerned that the suspect had a "biased intent because a Pride flag was displayed directly behind the vandalized window," according to the Facebook post.

A juvenile, who police determined acted alone, was identified as a suspect on June 7, the department said. The young person cooperated with detectives and was subsequently arrested, according to the Facebook post.

Police have referred the case to the Yamhill County Juvenile Department.

BB gun used to shatter Newberg Library's window

On the day of the incident, the Newberg Library shared a post on Facebook confirming that "no one was injured."

The library's post also said the weapon used to commit the incident was likely a 99W, a type of BB gun. The BB shattered the "new protective glass installed with grant funds in January 2024," but the original 1912 glass is "still intact," according to the library.

The shattered window is located on the southeast corner of the library, according to the social media post.

Once Newberg police announced they had an arrest, the library shared another Facebook post on June 7 thanking the department.

"Thank you to the Newberg Newberg-Dundee Police Department for their diligent work to resolve this case," the library wrote.
