(Nashville, TN)  --  A routine traffic stop is being credited for the discovery of a large marijuana grow operation. 

Metro Police say William Leader was pulled over Tuesday and pot was found in the trunk of his car.  Leader's arrest led officers to a home off of Old Charlotte Pike where 58 marijuana plants in various stages of growth were discovered.  As officers were leaving, David Hall pulled up and was arrested for having three mason jars of high-grade marijuana in his vehicle.
