SALT LAKE CITY (AP) — A Utah school district is investigating possible racism and bullying on a school bus after a video surfaced on social media. KSTU-TV reports the video shows middle school children gathering around a Black student while the bus is moving. It shows students surrounding a student, with one boy referring to him as “Black guy” and some poking him as he says, “stop touching me.”  The Alpine School District said in a statement that administrators have opened an investigation. The Utah County Sheriff’s Office has also been involved and is working to identify the students.
