The FBI is opening an investigation into offensive graffiti spray painted on the Islamic School of Rhode Island.

Authorities say security cameras captured a man vandalizing the West Warwick building on Saturday.

He painted several racial slurs across doors and windows of the school for children in kindergarten through eighth grade.

The school's principal is calling it a hate crime.

The vandalism took place just one day after a vigil was held at the school for three Muslim students who were murdered in North Carolina.
