Members of Drake's entourage are NOT talking to cops about the nightclub brawl with Chris Brown ... because they do not want to become "snitches" -- sources tell TMZ..
As one source put it, "We're no running-to-the-police ass n**gas."
TMZ broke the story ... Chris Brown and his lawyers have been cooperating with police.
As for Drake, law enforcement sources tell us the NYPD has spoken with his reps but they won't be able to speak with the rapper until his lawyer comes to NYC.
As for Drake's boys refusing to cooperate, as the adage goes ... snitches get stitches.
