Two people still on the run following an armored car robbery in Dallas Tuesday afternoon.
The robbery took place along the 8100-block of Lake June Road, Dallas police said, when the Dunbar Armored Car stopped to drop off cash at PLS Check Cashing at 12:40 p.m.
As the guard approached the door to the business, a white, Nissan Altima pulled up next to the armored car with two men inside wearing masks and hoodies.
The passenger in the Altima exited the car with a gun and ordered the guard to hand over the bag of cash. The guard complied and the men then drove off, leaving the guard uninjured.
The getaway car, which turned out to be stolen out of Duncanville, was found a short time later abandoned on the 1400-block of Conner Drive.
Officers began to search the area for the two men using K-9 units and the Dallas police helicopter. While the search continued through abandoned buildings and residential backyards, the Dallas Independent School District responded by locking down nearby John Quincy Adams Elementary School.
Though officers were spotted talking to two people during the course of the neighborhood search, they said they have made no arrests in connection with the heist and that they are actively looking for the men involved in the robbery.
Police have not said how much cash was stolen. Additionally, since the armed robbers were wearing masks, investigators have not been able to share a description of the two men.
The robbery is now being investigated by Dallas Police Robbery Detectives and the FBI Task Force.
