The 25-year-old employee said he had been working at the store for about a month when what started as a routine overnight shift suddenly turned violent.
One of the most recent victims was 76-year-old Jorge Medina, a resident in the West Concourse section of the Bronx.
The kidnapping and robbery happened around 1 a.m. on Sunday along Bronx Park Avenue.
Deputy Mayor Kaz Daughtry replenished the 10-year-old's piggy bank and gifted him an iPad from the city as a thank you for his bravery.
The victim was approached by three men on West 207th Street just after 4 a.m. on Friday.
A 99-year-old man was standing at an entrance gate for a residential building when he was approached by the suspect.
