ingress

Officials are continuing to investigate the cause of the water ingress.

The Belfast Trust said it recently completed investigatory work in two bedrooms to determine the extent of remediation work to rectify damage caused by water ingress.

Two roofing companies have told him there are too few rows of tiles, meaning the overlap isn't sufficient to prevent water ingress.

When asked how most contraband was smuggled into the prison, Will Styles said "there are a number of ingress routes".

"These are all gaps where water can ingress," Robin adds.
