The sheriff’s office said it had found no instances where Lake County courthouse workers were asked to remove their blouses at a security checkpoint.

A CBS 2 A report sparked the investigation after several employees working at the courthouse claimed that a security contractor asked them to remove their button-down coats as they walked through metal detectors.

Chicago-based Monterrey Security is engaged in security at the Lake County Circuit Courthouse in Waukegan.

Lake County Sheriff’s Chief of Staff Anthony Vega said the complaints came from one entry point “among many” that Monterrey security oversees.

On Saturday, Vega told Lake and McHenry County Scanner in an update that the sheriff’s office viewed surveillance footage from that entry point.

Several staff members and a command officer reviewed hours of footage from multiple angles, Vega said, adding that footage from another entry point was also reviewed.

No cases were found to support the allegations.

Vega said the complaints were never directly reported to the sheriff’s office, only to the media.

“We hope that in the future anyone who has any concerns or questions about the selection process will be directed to the appropriate channels so that we can respond appropriately in partnership,” said Vega.

The sheriff’s office said it has worked with management at Monterrey Security to ensure they understand and are trained in the protocols.

Vega also said county department heads have been made aware of the clarified testing guidelines so they can communicate with their staff.
