An executive of a Hyattsville-based construction company is facing criminal bribery charges.

A grand jury returned an indictment charging Potomac Construction Vice President Hardutt Singh with one count of bribery of a public official, the Maryland State's Attorney for Prince George's County announced Wednesday.

The indictment says Singh attempted to bribe an employee of WMATA, the agency that runs the region's Metro system, on Dec. 16, 2016. Potomac Construction, which declined to comment, lists WMATA as a top client on its website. It has completed multimillion-dollar jobs for the agency, including the $1.6M Vienna Metro station mezzanine extension and stair project and a $6M bus bay improvement project at the Franconia-Springfield station.

A conviction for bribing a public official can result in a prison sentence of up to 15 years. Maryland Assistant State's Attorney Joel Patterson is prosecuting the case. The issue is also being investigated by WMATA's Office of Inspector General, the FBI's Washington Field Office and the U.S. Department of Transportation's Office of Inspector General.
