In reply to Marcus Buckley: OK here's what I've found out.
The wall is closed as the SPA guy who is "in charge" made a verbal report to the management saying that the wall was unsafe due to people removing bolts that hold the panels together.
The wall has been closed to the public and only open to supervised groups (supervised by the sports centres own staff) for many months now. I assumed that if there was a safety problem then this would be sorted out in time for the winter indoor wall season, the sports centre are supposed to maintain the facility for several more years (a condition of the funding provided to build it) The recent news article would suggest that the wall in now permanently closed.
