PORTLAND, Ore. (KOIN) — A police investigation is underway after a noose was found on a fence behind the backstop of a baseball diamond in a park next to Bridlemile Elementary School in Southwest Portland, school officials confirmed to KOIN 6 News.

The Portland Police Bureau confirmed Tuesday bias crime detectives were investigating the incident. Officers said they learned the rope was possibly hung sometime on Thursday, Oct. 15.

When school administrators learned about the noose, they put into place the district’s response to hate protocols, reported it to the City of Portland and the Portland police, Regional Superintendent Esther Omogbehin said in a letter to parents.

“The Bridlemile team is consulting with district leadership about the best way to support staff, students and families. We will share more information early next week with specific details regarding next steps,” she wrote in part.

Omogbehin noted the racist history of the noose and how it can spark reaction and trauma.

“This kind of incident is not isolated to our community, but I know that we do not want to be motivated by fear and hate, and I trust we will come together to support each other and do the work necessary to continue to provide a caring, supportive and healthy environment for everyone in our community,” she said.

“This act is incredibly disturbing. Hate speech or symbols are never tolerated in any PPS school or anywhere in our District.”
