BILLINGS, Mont. (AP) — An asbestos screening clinic in a small Montana town where thousands have been sickened by toxic dust from a nearby mine has been abruptly shuttered by authorities following a court order to seize the clinic’s assets to pay off a judgment to the railroad BNSF.

The Lincoln County Sheriff’s Office closed on Wednesday the Center for Asbestos Related Disease in Libby, about 50 miles (80 kilometers) from the U.S.-Canada border. The town of about 3,000 people is near a mine that produced asbestos dust for decades, and the clinic has been at the forefront of efforts to help victims.
