"Pena admitted that he and his supervisor… were responsible for contracting with local vendors to purchase supplies to support humanitarian relief in Afghanistan," the release stated. "Pena admitted that he received from the vendors… a Rolex watch and $100,000 in total bribe payments."
Pena and his supervisor, the release added, awarded 217 such contracts worth approximately $30,760,255 from January 2008 through September 2009.
He also used the bribe money to purchase a Harley Davidson motorcycle, which he now has to forfeit along with the Rolex and cash, the release added.
The Special Inspector General for Afghanistan Reconstruction (SIGAR) has previously reported that billions of US taxpayer dollars have been wasted in Afghanistan because of contractor bribery schemes, fraud and gross overbilling.
In the first half of 2015 alone, at least five US military personnel have been indicted on bribery and theft charges in Afghanistan, according to the SIGAR.
