In early 1987, the firm Hawley Goodall, owned by Lord Ashcroft, bought the Indianapolis-based Crime Control Inc., the fourth-largest company in the U.S. security market, for $50 million. Later in the year, it bought ADT and moved to Bermuda. This purchase transformed Hawley into the leading security services business in the United States, and resulted in the majority of its revenues coming from the North American market. As a result of the acquisition, Hawley changed its name to ADT Limited and decided to refocus its business around security services. At the end of 1987, the company sold its North American–based facility services business to Denmark's ISS A/S. Notorious serial killer Dennis Rader worked for this company from 1974 to 1988.
