Two teenage girls were arrested Friday, nearly two months after police say they and a third person vandalized Plano West Senior High School with spray-painted vulgarities and racial slurs.

Alexandria Monet Butler and Elizabeth Joy Police, both 17, were charged with one count of criminal mischief causing damage to a school, a state jail felony. The two are students in Frisco ISD, police said.

Butler remains in the Collin County Jail, with bail set at $10,000; Police was released Friday after posting $10,000 bond.

Authorities are still looking for 19-year-old Tyrian Rankins.

Police were notified of the vandalism when a parent saw it while dropping off a child at the school early Feb. 27.

Photos circulated online that showed a number of vulgarities spray-painted on walls, doors and a school van — including the N-word and a drawing of a penis.

Plano West principal Kathy King said at the time that it was "disheartening" for students and faculty to see the school vandalized.

Police released surveillance footage of the vandals last month after being unable to identify them.
