Fourteen men were arrested in a multi-day sex trafficking sting at a Gurnee-area hotel in the north suburbs.

The Lake County sheriff’s office announced the arrests Wednesday as part of a national operation targeting the consumers of prostitution, known as “Johns,” the sheriff’s office said in a statement.

The sting used phony online ads selling prostitution and directed the men to a hotel in the Gurnee area, where they were arrested by undercover officers, the sheriff’s office said.

”Many of the individuals selling sex are not doing so willingly, a large number are being forced into involuntary servitude,” the sheriff’s office said in a statement.

In the last decade, the nation-wide anti-human trafficking effort has led to more than 10,000 arrests.

In Cook County, undercover officers arrested 157 men in a similar operation.
