The former mayor of Harvey, Ill., demanded thousands in monthly payments from a strip club to allow it to stay open, federal prosecutors said.

In 2003, prosecutors said, the mayor of a city in Northern Illinois sent a message to the operators of a local strip club: Pay me or I’ll shut you down.

The mayor of Harvey, Ill., a city of about 18,000 just south of Chicago, knew that the strip club allowed prostitution in a private area of the club, and he demanded $3,000 a month from the business to let it stay open, according to prosecutors.

According to a criminal complaint filed in U.S. District Court in Chicago, the club yielded to the threat, eventually even acquiescing to a demand from the mayor to double its payment to $6,000 per month. The scheme continued for about 15 years, prosecutors said.
