Ogden Dunes Officer Ed Clapp caught up with the witness and the bus around U.S. 12 and Ind. 149, near ArcelorMittal's east gate. Clapp activated his emergency lights and sirens near Wagner Road and U.S. 12 in an attempt to stop the bus, but Clark allegedly continued east on U.S. 12 at 30 to 35 mph, ignoring police.
