A Starbucks customer foiled a would-be armed robber — twice — over the weekend.

According to an Arlington County Police crime report, a man walked into a business on the 3100 block of Lee Highway just after 5 a.m. Sunday morning, brandished a firearm and ordered everyone to the back of the store. A customer with a venti-sized dose of audacity then intervened.

“A patron physically challenged the suspect causing the suspect to exit the business,” said the crime report. “The suspect immediately re-entered the business brandishing the firearm. Once confronted again by the patron, the suspect fled the scene on foot.”

“Arriving officers canvased the area and a K9 track yielded negative results,” the crime report continued. “No injuries were reported. The suspect is described as a black male, 20-30 years old, approximately 6’0, wearing a black winter jacket with a fur hood. The investigation is ongoing.”

Though police did not specify a business, a tipster said the robbery took place at the Starbucks in the Lyon Village Shopping Center, along Spout Run Parkway.

Asked about a possible surveillance image of the suspect, ACPD spokeswoman Ashley Savage said the department has “nothing for release at this time.”
