The victim told investigators he was working as a Lyft driver at the time and was stopped on the block waiting for his next job to dispatch.
While in his car, police said another vehicle pulled up next to him and the occupants asked for directions to a gas station, which he provided them.
Shortly after, the vehicle returned two more times.
The third time, police said, the vehicle stopped and two males exited; one male was armed with a gun and announced a robbery.
The victim stated he began fighting with the suspects when the armed male fired once.
The bullet struck the victim in his left hand which went through and into his chest. Police said the males got back into their vehicle and fled towards Berkley Street.
No arrests have been made.
Police are searching for three male suspects.
