A District man was sentenced to 10 years in prison Friday for his roles in the armed robberies of his ex-employer’s truck drivers as they delivered Apple products to stores, authorities said.

According to the U.S. attorney’s office for the Eastern District of Virginia, Avery D. Bines, 32, pleaded guilty to using a firearm during a crime of violence on July 9.

Authorities said Bines worked with conspirators who drove a vehicle into the side of a delivery truck outside Fair Oaks Mall in June 2011. After a conspirator blindfolded and bound the driver at gunpoint, authorities said, theydrove the truck to a nearby gas station where Bines and others stole about $41,000 of Apple products from the truck.

In October 2011, authorities said, Bines participated in another robbery of a driver in Prince George’s County in which the driver was bound and pistol-whipped and the robbers took about $71,000 worth of Apple products.

Bines was sentenced to five years of supervised release in addition to the 120-month prison sentence, authorities said.
