But Little said a more thorough review may take place afterwards.
"We need to know whether there is anything inside of those organisations which meant that they couldn't see what was happening or they simply didn't see, and if there were things that they should have seen that they didn't.
"We need to get an answer to that question fairly soon, the question then is whether we follow that up with a much more deep seated review that looks at what we need to do to change to make sure we never face this again."
He said the agencies feel a huge sense of responsibility and recognise there are questions to answer.

"I can’t advise a judge, they’re totally independent, but I think the judge might quite properly – anytime this man starts to rave about his ideology, close him down, and if he can’t be closed down, removed from the court.
"These guys are after the fame, the celebrity, the notoriety, that’s what motivates them – deny him that."
Goff said the alleged shooter's face shouldn't be shown and his name not mentioned.
