WESTFIELD, NJ — Westfield Police found that there was no threat to Roosevelt Intermediate School Thursday afternoon, according to Westfield Police Chief David Wayman.

The school had been placed on a “shelter in place” for 25 minutes during the school day after “inappropriate graffiti” was found, parents were told in an email sent by Principal Mary Asfendis.

Citing the ongoing investigation, Chief Wayman said that he could not comment on what the graffiti was.

“We’re fortunate in this town that our schools and police department work together cooperatively on a daily basis to ensure the safety of our students,” Superintendent Dr. Margaret Dolan said.
