The victim said he was sitting in his car at a gas pump in the 3200 block of Campbell at about 11:20 a.m. on June 26. when an unknown man jumped out of a dark green Jeep before approaching him.
Video then shows the suspect opening the man's passenger side door before snatching a bag and hopping back into the passenger's side of the Jeep. A second suspect, who was driving the Jeep, then sped off as the victim attempted to chase them on foot.
The victim also said he believes a separate vehicle was involved because he saw that driver interacting with the two other men just moments before the robbery. That driver was seen on video leaving the scene just seconds after they did.
