When making such a pertinent comment a source would be useful.
The Guardian does not mention it either, both however state that Quick spoke to Cameron and asked for help in locating Green, and specifically points out that he did not reveal the intention to arrest him.
The officer admitted he had taken a "conscious decision" not to tell Cameron that Green was going to be arrested.
Nor do any other of the accounts of the Commons Committee make the statement that Quick told Cameron he was going to search his offices.
Nor can I find the statement on the website of the Committee
concerned, as yet I have not trawled through the video of Quick giving his evidence as it is 1hr 53 mins long and I have not the time at the moment.
Edited to add
Having just found the relevant part of Quick's testimony, he never states that Green's parliamentary offices were to be searched, just that "premises" associated with Green in his conservation with Cameron.
