Doctors treated nearly 20 kids after they apparently took some unknown pills at two Chicago schools.

Fifteen of the kids were from Air Force Academy on the South Side.

Three others were from McClellan Elementary School.

Police say the four kids they think are responsible were among those doctors treated.

They've been charged with possession.

The drugs are being tested at a lab.

Chicago Public Schools says it's also investigating what happened.
