The investigation has completed however we are not yet in a position to publish the report.

....
The IPCC have not yet issued any public statement at the conclusion of this investigation. The matter is connected with a second investigation looking into some of the post incident handling of the incident and it had been hoped that the two matters would be reported on together, however the second investigation has suffered some unexpected delays.

I have alerted the Commissioner responsible for the first investigation to the issue and it will be a matter for her as to whether she decides to put something out publicly now or wait for the second investigation to conclude. I hope to have a conversation with her this week and provide you with an update in due course.
