Two dozen elementary students in Texas were forced to pull their pants down after human waste turned up on the gym floor.
School officials at Gustine Elementary separated the boys and girls in different rooms.
The students were told to lower their pants so school workers could try to find evidence, pointing to the person behind the waste.
Some parents are furious.
The superintendent would not condone the search, saying partially strip-searching students went too far.
The district is investigating.
