Following previous incidents at the train depots, the Public Transport Operators (PTOs) have taken steps to enhance security at their train depots. These include increasing the number of security personnel and frequency of security patrols at the depot, as well as upgrading the perimeter fencing around the depot.  Strict measures on daily inspection of the interior and exterior of trains prior to departure from the depots for commuter service also help to ensure that the safety of commuters is not compromised. LTA will continue to work with the PTOs and relevant agencies to take the necessary measures needed to strengthen the security of our PT network. LTA will also continue its investigations into this incident.
