Minneapolis Public Schools is notifying parents after a racial incident at Washburn High School, KSTP reports.

According to a letter to parents, a small group of students dangled a dark-skinned baby doll by its neck with a piece of string in a stairwell on Jan. 11. The incident was recorded by students and images were posted on social media.

"This is an extremely disturbing occurrence and not reflective of the Miller Pride that we promote. Such insensitive behavior is intolerable in our school and school district, both of which are full of diversity and rich in culture," said Principal Carol Markham-Cousins.

KARE 11 reports at least four students were involved in varying degrees.

The school says disciplinary actions will not be released due to to student privacy concerns.

KARE 11 published an image of the doll.
