The president of a national railroad employees union has been arrested and charged with bribery.

Edward Rodzwicz, who heads the Brotherhood of Locomotive Engineers and Trainmen, is accused of taking $20,000 in bribes from a St. Louis lawyer. In exchange, prosecutors say Rodzwicz allowed the lawyer to stay on a list of attorneys approved to handle injury cases for union members.

That attorney was supposed to be removed from the list due to alleged ethical violations. But prosecutors say that in exchange for cash payments, Rodzwicz sent a letter allowing the attorney to stay on.

Rodzwicz was arrested Tuesday morning at his home in Avon, Ohio. A criminal complaint was filed against him last week in federal district court in St. Louis.
