Cubs Employee Hospitalized After Contact With 'Foreign Substance' Near Wrigley Field

A Chicago Cubs employee was hospitalized after opening a package containing a suspicious substance in a building near Wrigley Field.

A Hazmat Level 1 call went out Tuesday afternoon for 1101 West Waveland Avenue (the American Airlines Conference Center), and police and firefighters responded to the scene. Fire officials say a man opened a package at the scene then transported to Advocate Illinois Masonic Medical Center.

The man was burned by some type of powder enclosed in an envelope. A bomb squad remained on the scene throughout the afternoon.

The Cubs released the following statement: "This afternoon, a member of our security team detected a foreign substance that was contained in a small package delivered to our offices at 1101 West Waveland.

"We immediately notified authorities, which prompted a Chicago Fire Department hazmat response. The employee noticed an allergic reaction and was transported to the hospital as a precaution and has since been released.

"At this time, we have not been asked to leave the building or shelter in place while the safety assessment and investigation is underway."
