Attorney General Lisa Madigan’s office is suing transportation company Suburban Express and its owner over problems with discrimination, harassment and privacy.

The company provides bus service for college students to and from home. Attorney General Madigan says an investigation found the owner, Dennis Toeppen, discriminated against customers because of race, especially asian students, and sent out racist marketing emails.

The suit seeks to shut down the company. Madigan’s office also filed a temporary restraining order to stop Suburban Express from harassing customers and publishing their personal information.
