The Game is accusing Meek Mill of snitching because of the investigation into the robbery of Sean Kingston in an L.A. nightclub.
Game ripped into Meek onstage Thursday night, but it was unclear why he was calling him a snitch. Sources close to both rappers tell us this goes back to a June incident at Penthouse Nightclub & Dayclub.
TMZ broke the story ... Kingston got smashed in the head with a bottle and then the attackers snatched a $300k chain off his neck. Both Game and Meek were in the club that evening.
We're told Game believes Meek dropped a dime on him to Kingston's people, and told them Game or someone in his crew was involved in the heist.
Onstage in Miami, Game strongly hinted investigators questioned him about the crime.
Our law enforcement sources tell us Game was never a suspect ... and the investigation's been closed because Kingston's no longer cooperating.
