The following factors might have contributed to providing Mas Selamat more time to make good his escape

First, there was a physical security breach as the ventilation window in the toilet – from which Mas Selamat made his escape – did not have grilles.

Second, the guards watching Mas Selamat allowed him to close the door of the urinal cubicle when they should not have done so.

And third, there was a physical weakness in the perimeter fencing outside the Family Visitation Block, where the toilet was located, which made it easier for Mas Selamat to get out of the detention centre's premises.

In addition, the CCTV coverage of the area was being upgraded to add motion-detectors, but the cameras were not yet operational.

A packet of 7 rolls of toilet paper was found on the ground adjacent to the external wall, which he could have used to break his fall when he descended.
