ARLINGTON, Va. (WUSA9) -- An armed robbery and carjacking suspect was arrested in Arlington on Tuesday, and police are searching for the handgun he used during the crime.
At 2:13 a.m. Tuesday morning, a suspect identified as Antonious Sallis, age 33, entered a 7-11 convenience store, held a knife to the throat of one of the sales clerks and demanded cigarettes and cash from the registers, police said.
Sallis was also armed with a handgun.
As Sallis was fleeing the scene he demanded the wallet of a delivery truck driver who was at the 7-11 making a delivery. Sallis forced the delivery truck driver to start the truck in an attempt to use it as a getaway vehicle, but he was unable to disengage the air brake, police said.
