LISLE – A call to police regarding a suspicious powder found in a letter mailed to a local employer turned out to be the result of an innocent mistake.
The Lisle Police Department and the Lisle-Woodridge Fire District responded at 11:30 a.m. April 29 to Navisar Corporate Headquarters, 2701 Navistar Drive, after receiving reports that the company had been mailed an envelope containing a white powder, according to Lisle Police Department Deputy Chief of Administration Ron Wilke.
The letter was sent by a former Navistar employee, Wilke said. Its contents were not threatening and the powder was determined to be a fiber supplement that had spilled near the envelope before the letter was put in the post.
The sender had no intent to harm or alarm the envelope’s recipients, according to Wilke.
“It was an innocent misunderstanding,” he said.
According to Wilke, no charges were filed.
