A man who pleaded not guilty to breaking into the home of actress Sandra Bullock has been charged with possessing an arsenal of heavy weapons authorities say they found at his home.

The Los Angeles County district attorney's office charged Joshua James Corbett with 19 felony counts including seven counts of possessing a machine gun, two counts of possessing an assault weapon and 10 counts of possessing a destructive device. The destructive devices were described as tracer ammunition.

Corbett pleaded not guilty Wednesday, and bail was set at $2 million.

There's no claim that Corbett brought weapons when police say he jumped Bullock's fence and broke into her home June 8.

If convicted of the new charges, Corbett could face up to 12 years in prison.
