The MBTA fired two more employees in connection to a criminal investigation into allegations they were working on personal or private vehicles during work hours at a train yard in South Boston, the agency confirmed to the Herald Saturday.

Agency officials have let go a total of eight employees, with the latest terminations taking place about three weeks ago, MBTA spokesman Joe Pesaturo said. One employee has received a multi-day suspension and two others remain on administrative leave while the probe continues, Pesaturo said.

MBTA General Manager Phillip Eng said the alleged actions at the agency’s Cabot Yard facility not only “discredit” the employees and their families but also their colleagues.

“That’s something that we are going to continue to stress internally. That’s not acceptable. And when we identify those things, if those are occurring, we’re going to take swift action. That’s how we rebuild public trust, and that’s how we demonstrate that we’re going to be putting taxpayer dollars to better use,” he said during a pre-recorded interview with WCVB published Friday.

After an October meeting, Eng confirmed the probe into the employees and said the MBTA Transit Police Department was investigating the allegations for “potential criminal activity,” The Boston Globe reported.

In an earlier statement provided to the Herald, Eng said the alleged misconduct “does not reflect the values of the MBTA community, and it has not and will not impact the progress we are delivering across the system.”

“We are taking these allegations very seriously, as we have an obligation to the public we serve and to our workforce to ensure that every employee meets the highest standards of conduct. We will continue to take all necessary actions to ensure accountability based on the findings of the investigation and prevent a situation like this from happening again,” he said.
