(CNN) -- Six middle-schoolers in suburban Phoenix, Arizona, were taken to area hospitals Friday after a suspected student was caught handing out prescription pills on the school playground, authorities said.
Ambulances and parents took the sixth-grade students for treatment after the incident at Wigwam Creek Middle School in Litchfield Park, Maricopa County Sheriff's Office Detective A.D. Douglas told CNN.
It was not clear Friday evening whether the children were admitted to the hospitals or whether the students ingested the unidentified pills.
A teacher observed the activity and put a stop to it, Douglas said.
A search of the unidentified suspect's backpack revealed an assortment of prescription pills and individually packaged marijuana, he said.
A search warrant was being drafted for the residence of the young suspect, Douglas added.
Arizona Child Protective Services will investigate.
