Federal agents want to seize dozens of properties and bank accounts they said are linked to an $18 million illegal slot machine operation throughout Baltimore County.

Prosecutors allege that Cockeysville resident John Zorzit supplied illegal slot machines to about three dozen liquor stores, taverns and inns between 2003 and 2006, according to an affidavit filed with a civil complaint in U.S District Court last week. Authorities allege that several agents received cash winnings after playing Zorzit’s machines undercover and that the devices were equipped with illegal “point clearing” mechanisms.
