How do I find out if a company is in violation of bankruptcy, and is there a way to report it?

My former employer of a small business is restructuring under bankruptcy. I know he has created a "sister company" that does the exact same thing and is trying to funnel his old customers to his new company. Using the failing companies advertising dollars to get the new business of the ground seems like stealing from the people he owes money to. To make things more difficult for me I am a "disgruntled employee" and a competitor. I don't want my judgement to be clouded just because I don't like the guy. There is also a friend of mine still at the old company who relies on that job. I'm not asking you to solve all of life's problems, but it would be nice to know my options...
