Clown costumes are being banned from New Haven Public Schools as Halloween approaches, following the hysteria disrupting classrooms and communities across the country.

The directive was made as authorities investigate two Instagram accounts that appeared to make targeted threats at the Naugatuck community: “If you go to Career watch out,” one post said and another saying “u really think it’s fake, wait and see,” reported Fox 61.

School officials said clown costumes and "symbols of terror" will not be tolerated.

One of those photos was of the clown character Pennywise from the film “It” based on a Stephen King novel.

“At this time there is no indication this incident poses any real or substantial threat to New Haven Public Schools or students,” the school district said in a statement.

“We do however take these incidents very seriously; In light of this incident, we will continue to monitor the situation throughout the week and take all necessary precautions to ensure student and staff safety in all our schools.”

College campuses aren’t immune to the clown panic pandemic, either. Quinnipiac University had a scare Monday night of a clown with a gun on campus, but Public Safety squashed the rumors on their Twitter account.
