A former Fairfax County police officer was charged Monday with stealing more than 2,500 gallons of gas while he was an officer.

Lon A. Wolber submitted his retirement from the police force the day after he was confronted with evidence of his theft, Chief of Police Edwin C. Roessler Jr. said in a video about Wolber’s indictment which the department posted on YouTube on Monday.

Roessler explained that county employees use an access code to obtain fuel at a county pump. A police department employee noticed unusual activity at a county gas pump in October, and the subsequent inspection of the fuel access computer’s records indicated that someone had been obtaining gas using retired employees’ codes and the codes of active employees who were working in other areas.

Wolber was removed from police work and placed on administrative leave, due to the investigation into the gas theft, in February, Roessler said. Wolber, who had served on the police force for 28 years, quickly decided to retire.

Roessler said that Wolber was not using the gas for his job as an officer.

The average American uses far less gasoline annually — 435 gallons per year, according to Forbes magazine — than Wolber allegedly stole.

“The criminal actions by Mr. Wolber were thoroughly investigated and the indictments are reflective of demonstrating that such actions by any employee, whether active or retired, shall not be tolerated,” Roessler said in the video.

Wolber was charged Monday with embezzlement and misuse of public funds.
