Investigators have released surveillance video showing the person wanted for a recent attempted robbery of a postal worker.
The incident happened July 5 in Little Havana.
The video also shows the getaway car, a silver Camaro, driving around the postal worker at least three times before fleeing the area.
Police describe the attacker as a black man in his 20s with a stocky build.
Last week another mail carrier was attacked in North Miami by two men. Those thieves got away with the woman's master key and vehicle key.
Postal investigators said four mail carriers have been attacked or robbed so far this year.
