A Metro worker who managed the transit agency’s surplus-equipment warehouse was charged Tuesday with illegally pocketing $60,000 in proceeds from the sale of used heavy machinery, including a bulldozer and an asphalt roller, Prince George’s County authorities said.

Adrian Sclawy, 61, of Annapolis, who was fired by Metro after transit police began looking into the alleged fraud last summer, was indicted by a Prince George’s grand jury on a charge of felony theft, said John Erzen, a spokesman for the state’s attorney’s office. Erzen said Sclawy remains under investigation because bank records show that, in addition to alleged ill-gotten $60,000, he deposited about $75,000, the source of which has not been explained.

Sclawy, whose job involved selling surplus Metro equipment from the warehouse in New Carrollton, instructed buyers to pay with bank checks with the payee line blank instead of the transit agency in several instances, Erzen said. Sclawy allegedly told the buyers he would use an official Metro stamp, but made the checks out to himself. Erzen said there were a number of fraudulent transactions from 2009 until last year.

It was unclear early Tuesday afternoon whether Sclawy was in police custody. Metro and the state’s attorney office planned to release more details of the case later in the day.
