The confrontation escalated, and the suspects allegedly punched and kicked the victim. Police said one suspect stole the victim's fanny pack while another sprayed him with mace.

The suspects exited the train at the 167th Street subway station and ran away, according to police.

The victim was taken by Transit District 11 officers to BronxCare Health System for treatment and is expected to recover.
