Fairfax County police think two men could be behind a string of armed robberies in Northern Virginia and Fredericksburg.

The most recent robbery took place at a convenience store in the 6500 block of Edsall Road about 1 p.m. Wednesday, police said. Two men approached a clerk with items, as if to pay. They then assaulted the clerk, took money and fled.

In three other robberies, two men entered 7-Eleven stores, displayed a handgun, took money and fled, police said. The 7-Eleven robberies occurred at the following locations:

●Aug. 12 — 8146 Old Mount Vernon Rd., Alexandria.

●Aug. 21 — 2305 Huntington Ave., Alexandria.

●Aug, 24 — 7225 Old Keene Mill Rd., Springfield.

In a fifth case, suspects attempted to rob a 22-year-old woman while she was walking in the 6300 block of Backlick Road in Springfield on Aug. 22, police said.

The same individuals are believed to be responsible for numerous armed robberies in Prince William County and Fredericksburg, police said. Investigators consider both suspects to be armed and dangerous. If seen, police said people should not approach the men and should instead call 911.

Both suspects are black, between 20 and 26 years old and 150 to 180 pounds, police said. One suspect was seen in all-black clothing. He was between 5’6” and 5’8” and had a medium build. He wore a gray baseball cap with a white insignia.

The other suspect was about 5’11’ to 6’1” and wore a hooded sweatshirt and black pants.
