PASADENA — Officials inspected a suspicious envelope received at a Pasadena insurance office Thursday, ultimately determining a powder inside to be harmless, police said.
The envelope was discovered about noon on the 8th floor of an office building at 210 S. Lake Ave., Pasadena police Sgt. John Luna said.
After spotting a powder inside, employees called authorities.
Pasadena firefighters responded and tested the substance, ultimately finding it to be non-toxic, Luna said. More tests were needed to identity the substance definitively, however it was initially believed to be corn starch.
No letter or threat accompanied the powder-filled envelope, police said.
