Officials with the Harlan Police Department say a suspicious substance discovered at CDS Global Thursday afternoon, was NOT harmful. At around 12:30-pm CDS Global in Harlan received an envelope containing an unknown white powder. Local law enforcement, Shelby County Emergency Management, Shelby County Public Health, Harlan Fire Department and other local agencies responded to the call from CDS.

The FBI, US Postal, The 71st. Civil Support Team, and Iowa Homeland Security and Emergency Management, and Iowa State Patrol were called to assist. Until the makeup of the substance could be determined CDS Global was locked down.

Following preliminary testing of the substance employees were allowed to leave CDS Global. Authorities were able to determine that the substance posed no threat at any time to CDS employees or to the public, and  CDS Global was told to resume normal operations at approximately 7:30 PM, Thursday.

The origin of the letter remains under investigation by Federal agencies.
