A bomb threat prompted the evacuation of a library in Libertyville Tuesday evening on the same day numerous other libraries in the Chicagoland area received bomb threats.

The Libertyville Police Department and Libertyville Fire Department responded around 5 p.m. Tuesday to Cook Memorial Library, 413 North Milwaukee Avenue in Libertyville.

Libertyville Deputy Police Chief Chad Roszkowiak said a bomb threat was reported and the facility was evacuated before police and fire crews arrived.

The bomb threat was determined to be not credible and the library returned to normal operations, Roszkowiak said.

Further information on the case was not released.

The threat was one of many made to libraries throughout the Chicagoland area Tuesday.

In Chicago, an employee received an anonymous email saying there was a bomb inside the Harold Washington Library around 5:30 p.m.

Three public libraries in Aurora were evacuated around the same time for bomb threats.

Threats were also made to libraries in Evanston, Schaumburg, Addison and other suburbs.

Late last month, the Warren-Newport Public Library in Gurnee was evacuated following its at least third bomb threat in less than two weeks.

A statement said the Warren-Newport Public Library has received multiple bomb threats delivered by email and other electronic methods of communication.

In each instance, library staff worked with the Gurnee Police Department to evaluate the threat and clear the building before resuming operations.

Police say an investigation into the origin of the threats is ongoing.

The FBI Chicago told Lake and McHenry County Scanner in August they could not confirm or deny whether they are involved in the investigations but said they take threats to the public “very seriously” and often work closely with local law enforcement.
