Four more Massachusetts state troopers are being investigated for a possible role in the ongoing overtime scandal.
Investigators say the four troopers were identified during an internal audit into overtime pay and actual time worked.
So far, 46 current or former state troopers have been linked to the scandal.
The troopers all were part of Troop E, the division that patrolled the MassPike that has since been disbanded.
Officials say that all are accused of getting paid for details that they did not work.
