The incident occurred right after Naperville Central's sophomore football game a week ago.

The 15-year-old player discovered a racial slur on the front of his locker door.

The teen's mother said she reported the incident to the school, but she has not yet determined who was responsible for the letter.

The teen's mother said the coaches apparently spoke to the team about it, but no one took responsibility.

The school district sent an email to parents describing the incident and saying, in part: “This incident is currently under active investigation and we are committed to providing necessary support to all affected students.”

The school also said it immediately launched an investigation into what it called an incident of hate speech.

Some DuPage County civil rights advocates say the response has been inadequate.

“They should have given him a new locker and taken the door off of it,” said Michael Childress, DuPage County NAACP president.

The incident was also reported to the Naperville department's school resource officer, who said the matter is under investigation.

The teen's mother said she believes it should be considered a hate crime.

Naperville Central's sophomore team plays Friday night, and Quiana Richardson said her son plans to play.
