Indianapolis-based Celadon Group, Inc. has filed for Chapter 11 bankruptcy and shut down all of its business operations. This will affect approximately 4,000 employees. Celadon’s former chief operating officer and chief financial officer were indicted on multiple federal fraud charges last week, related to an alleged securities and accounting scheme that resulted in a more than $60 million drop in shareholder value. Founded in 1985, Celadon grew into the largest provider of international truckload services in North America with a fleet of 3,300 tractors, 10,000 trailers and nearly 4,000 employees.
