Federal officials have offered a $50,000 reward for information that will lead to the arrest and conviction of a man authorities say robbed a post office in Largo on Wednesday.

At about 7 p.m., a man wearing a black jogging suit walked into the Largo-Kettering Post Office on Apollo Drive demanding money from a postal worker, according to officials with the U.S. Postal Inspection Service.

“The suspect left with an undisclosed amount of cash,” according to a statement from the inspection service. “There were no injuries.”

The post office, located in Prince George’s County, was closed to the public at the time and there were only a few employees on duty during the robbery, said Tom Ouellette, a spokesman for the U.S. Postal Inspection Service.

Authorities don’t believe the robbery is connected to other postal-related crime the region has seen in recent months, Ouellette said.

In January, a masked man robbed a post office in Alexandria and five days later a letter carrier was robbed while delivering mail there.

Last week, a letter carrier was robbed and tied up in Northeast D.C.

And in November, Tyson Jerome Barnette was fatally shot while delivering mail on his route in Cheverly.

“There’s no evidence to suggest these crimes are connected,”Ouellette said. “The two crimes in Prince George’s County share little in common and Postal Inspectors have made arrests for both of the crimes committed in Alexandria.

Ouellette said robberies of post offices are not very common among the more than 30,000 facilities across the country.

“The Postal Inspection Service has in place security training programs for its employees, routinely conducts risk assessments, and adopted additional measures that help keep these crimes at a minimum,” Ouellette said.

Officials are asking anyone with information about the Largo robbery to call 877-876-2455.
