A Fort Wayne business that posted a sign barring Burmese immigrants from entering could face a civil rights complaint.

Ricker Oil Co. president Jay Ricker has apologized for the sign posted by an employee and says the business welcomes all customers. But director Gerald Foday of Fort Wayne's Metropolitan Human Relations Commission says he is considering filing a complaint.

The sign attempted to bar Burmese people "for sanitary reasons."

Fort Wayne is home to about 5,000 Burmese, the largest concentration in the United States. Many chew betel nut and spit the residue, which can result in red stains.

Health department spokesman John Silcox says businesses can't banish an entire group because of an individual's actions.
