MAPLE GROVE -- Students at a suburban Minneapolis high school have been greeted with messages of love the day after racist graffiti was discovered in a school bathroom.

When students walked into Maple Grove Senior High School on Thursday, they were met with welcoming cheers and notes with messages such as "Love always wins."

On Wednesday, students posted on social media about racist graffiti found at their school, which included messages such as (hashtag) "#whitesonly" and "#gobacktoafrica." Another area included a racial epithet.

In a statement, Principal Bart Becker said the racist messages "endanger the safety of our students and staff of color, and create a climate that is not conducive to learning."

The district and Maple Grove police are investigating to determine who wrote the graffiti.
