FREDERICK (AP) - Frederick County's rescue service said account information from the ambulance billing system was stolen and given to a theft ring.
A spokesman for the Frederick County Division of Fire and Rescue Services said Friday that the company that provides data services for ambulance service learned in October that information had been illegally accessed.
The company, Advanced Data Processing Inc., said some individual account information had been disclosed to a theft ring suspected of filing fraudulent federal tax returns.
The theft included ambulance data from Frederick County and First Response Medical Transportation Corp.
Advanced Data Processing said it has notified affected people. Anyone who believes they were affected but not contacted are urged to go to www.myidcare.com/intersecurity.
