The inspector general says a number of the cases involve workers pushing a button that permits emergency vehicles to go through a cash lane without paying. But according to Jim Wagner, employees were using the button to allow friends and family to pass for free. Others pushed the button and pocketed the money they collected.
Wagner explained why Tollway authorities became suspicious.
"With the advent of the IPASS, the majority of emergency vehicles are obviously going to go through the IPASS lanes," said Wagner. "Very rarely would they even go through a gated toll lane."
Wagner says cases involving theft of more than $500 have been referred to prosecutors.
