HOLLAND (WKZO) -- Holland police and federal agents have made a huge gang bust, with more than 30 alleged Latin Kings members indicted on federal charges.  Twenty-eight of the 31 suspects were arrested Tuesday, and ATF agents say their investigation is not over.  Police say the bust was the result of 20 years of investigative efforts, and say when federal and local authorities got on the same page in 2010, things came together quickly.
