Parents at an upstate New York middle school have accused two school employees of telling four 12-year-old Black girls they had to be strip searched because they were suspected of drug use.

The girls’ parents claim the assistant principal and school nurse at East Middle School in Binghamton strip searched the girls on Jan. 15, traumatizing them, according to HuffPost.

The employees reportedly thought the girls were doing drugs because they were acting “hyper and giddy,” said the advocacy group Progressive Leaders of Tomorrow, which is representing the parents.

The Binghamton School District denied the claim and said its staff conducted a “medical evaluation” and that it “may require the removal of bulky outside clothing to expose an arm so that vitals like blood pressure and pulse can be assessed,” according to BuzzFeed. “This is not the same as a strip search.”

The Progressive Leaders of Tomorrow disagree with the school’s version of events and said three of the students had to strip to their bras and the other student stripped to her bra and underwear.

“The children were instructed to remove their clothing, and felt shamed, humiliated and traumatized by the experience,” the organization said in a statement to HuffPost.

The school did not find any drugs on the students.
