Two teenage boys selling water on an interstate exit ramp were arrested Wednesday evening after one allegedly shot at a couple who refused them.

The boys first tried to sell to a woman as she exited I-285 South onto Martin Luther King Jr. Drive, according to an Atlanta police incident report obtained by AJC.com. When she declined to buy a bottle, both suspects allegedly “became irate,” starting an argument.

The two suspects are a 15-year-old boy and Eric Roberson, 17, of Atlanta. The woman said Roberson “approached her vehicle in an aggressive manner, throwing a bottle of water at her” as she drove away, the report said.

The woman went home to get her husband, and both returned to address the teens, the report said. As they returned, the juvenile said, “Man, I knew we was going to have to dump on him” before pulling out a handgun, the report said.

The 15-year-old fired several shots as the couple drove away, the report said. They were unharmed and called police around 6:45 p.m. from the parking lot of the Cascade Skating Rink. Officers later located the teenage suspects based on the description of two witnesses.

They found the teens at a home, but officers were unable to find the firearm, the report said. The juvenile’s mother told officers she “just left y’all up there selling water. What happened?”

While in custody, Roberson is accused of threatening an officer by saying, “I know your name. I am going to come and see about you when I get out.”

The 15-year-old was arrested on charges of aggravated assault and possession of a firearm during the commission of a crime and taken to the Metro Regional Youth Detention Center. He is not being named because he is being charged as a minor.

Roberson faces misdemeanor charges of terroristic threats and disorderly conduct. He bonded out of the Fulton County Jail the next day for $2,000, jail records show.
