Chris Brown has spoken with New York Police Dept. detectives about Tuesday altercation which law enforcement sources told his lawyer that he given the NYPD “physical evidence” which allegedly shows Drake was involved in the melee.

We’re told Chris’ lawyer, Mark Geragos, went to the NYPD late Thursday to present evidence showing that Drake and Meek Mill were the aggressors, but earlier in the day Chris spoke with Detectives at an undisclosed location in NYC.

We’re also told Drake is not currently a suspect.

On the other side, we’re told Drake has been “cooperating” with authorities, but we do not know if he has spoken to cops — it appears his representatives have had conversations with detectives.

Sources tell us … the bad guy here may be someone in Chris’ camp, who was inciting Drake and his people all night.
