Cops say Baker and Dunbar were allegedly hanging at a cookout — playing cards and video games — when an argument broke out and Baker whipped out a semi-automatic firearm.

Cops say the men began to rob party guests … with Dunbar assisting in taking watches and other valuables at the direction of Baker.

At one point, cops say Baker directed a 3rd man — who was wearing a red mask — to shoot someone who had just walked into the party … but fortunately, no one was actually shot.

One witness told cops they had met Baker and Dunbar at a party a few days earlier in Miami — at which the NFL players had “lost” around $70,000.

One witness told cops the men were gambling again at the May 13 event … when an argument broke out and Baker allegedly flipped a table and busted out his piece.
