The headquarters of the Daily Herald newspaper was evacuated Wednesday morning over “suspicious,” powder-covered letters that were ultimately deemed harmless.
Police and fire crews were called to the building at 155 E. Algonquin about 7 a.m., Arlington Heights Police Sgt. Thomas Henderson said.
A mail clerk called 911 after he brought mail back to the building from the post office, and noticed some “suspicious letters” that had glitter and powder on them, Henderson said.
The building was evacuated as a precaution, and U.S. Postal Service inspectors found the substances did not pose a threat, police said.
No injuries were reported. Staffers have since been allowed back inside the building, according to the newspaper’s Twitter account.
