Rapper Troy Ave is his brother’s keeper … and he proved it, large time, by opening fireplace on a gunman who ran up on his pal, celeb chef Geoff Cole.

The shootout went down within the San Diego space — dwelling safety footage reveals Geoff pull up at dwelling in his Bentley, Troy will get out on the passenger aspect … and as each males are strolling towards the storage, a would-be robber sneaks down the alley and fees at Geoff.

The Brooklyn MC instantly reacted, reaching for his personal handgun because the gunman fumbled an obvious weapon — and Troy seized the chance to begin taking pictures and chasing the man again into the alley.

It is unclear from the video if any of Troy’s photographs — he squeezed off a minimum of 2 rounds — hit the suspect, however Geoff is giving him props for saving the day. As he put it on IG, “s/o 2 my BROTHER Ave for Holding it Down in a scenario the place most woulda RAN or FOLDED.”

Though Geoff simply posted the video of this incident, we’re advised it really occurred again in mid June. He and Troy had been out celebrating the success of Chef Fest … a culinary occasion held final month in San Diego.

We have reached out to reps for Geoff and Troy … in addition to cops in San Diego to learn how this ended.
