MAPLE GROVE, Minn. - School administrators say they've identified and disciplined the student responsible for the racist graffiti at Maple Grove Senior High.

Photos of the graffiti, which exploded on social media earlier this month, were apparently taken in a boys bathroom at the school. The messages appeared on a door and a toiletry cover. They include the words "#gobacktoafrica", "#whitesonly" and "#whiteamerica". It also included the pro-Trump messages "Trump Train" and "Make America Great Again".

Officials at Maple Grove Senior High say they've launched an investigation into apparent racist, pro-Donald Trump graffiti.

In a letter to parents, Osseo School District Superintendent Kate Maguire said administrators identified the individual who they have determined wrote the messages and took appropriate disciplinary action. Maguire could not say what the discipline entailed citing student privacy laws, but said school board policy allows for a range of consequences that enable administrators to apply discipline according to the seriousness of any situation. "We found this to be an extremely serious incident," Maguire wrote.

She added the Maple Grove Police is still conducting its own investigation.

The school and district is taking several steps to promote respectful and constructive conversations about race. They include student, family and community listening sessions. The district's 4th annual Community Forum on Race is scheduled for 11 a.m. to 3 p.m. on March 11, 2017. The public is invited to attend. More information will be available on the District 279 website.

"I also want to emphasize that the long-term work of interrupting racism in our schools and communities will require all of us working together and taking actions that are sustained over time, both in schools and in the greater community," Maguire wrote.
