BILLINGS, Mont. - Montana's attorney general has launched an investigation into a California company's plan to take over the city of Hardin's $27 million jail, following revelations that the company's lead figure is a convicted felon with a history of fraud.

Michael Hilton, who formed Santa Ana, Calif.-based American Police Force in March, came to Hardin last month promising to fill the city's never-used jail and build an adjacent military and law enforcement training center.

Hilton has a decades-long track record of fraudulent activities and spent several years in a California prison on grand theft charges. The native of Montenegro uses at least 17 aliases.

Attorney General Steve Bullock said Thursday he is asking Hardin officials for all documents related to their dealings with Hilton and American Police Force.
