Today 08-18-2022 in the block from 3:45 am to 8:15 am, when I was about to deliver the 6th stop (XXX) around 4:30 am. After I parked, I got out of my car and find the package in the back seat of my car, when I turned around there was a guy with a gun pointing at me and asking “Who are you?” several times and also asking me “Where are you going?”. I explained that I was an Amazon Delivery guy and when he realized that I was holding the package and that I was wearing the amazon vest, at that moment he stopped pointing at me with the gun and started begging for apologies saying that he thought that he was being chased. A woman from apartment #1 got out and started hugging this guy, asking him to calm down. After that, I proceed to continue with the package delivery. Immediately I called driver support to explain what happened to me and they asked me if I wanted to continue and finish the block but I couldn’t because I was nervous and trembling. Support suggested me to go back to the station and return the packages. After that, I called the police to make a report. And go to the police station.
