Armed robbers stole the van of a courier making a delivery to a Waldorf, Maryland, pharmacy Tuesday morning.

It happened around 11 a.m. on the 12100 block of Old Line Center off Leonardtown Road, the Charles County Sheriff’s Office said.

As the courier was making a delivery, two suspects approached him and tried to force him into his van. He was able to get away and call for help, but the pair took the delivery van and left the scene.

The van was later found abandoned in D.C.
