The 36-year-old was working his second job delivering pizzas when he was ambushed.
Caballero was taking an order to an address on Ohio Avenue in Norwalk.
But, the delivery call, wall all a set up.
When Caballero pulled up to the address, the suspect met him in the driveway.
He told Cabellero he didn't have enough cash for the order, but if he followed him back, his mother would pay by credit card.
Instead, the suspect walked over to a pile of garbage bags and pulled out a machete.
While all of this was going on, a second suspect rifled through Caballero's car, stealing a GPS unit.
The two then ran away.
Caballero is not the only victim.
Just last week, another driver was robbed, and in the last three months there have been five pizza deliverymen robbed in Norwalk.
Police say they don't believe the crimes are linked, but food delivery workers are often targets.
Law enforcement officials say all delivery men should be careful and take safety precautions.
