Statement to reporters in crowd about rental agreement (5,7)
I believe the answer is:
press release
'statement to reporters' is the definition.
'crowd about rental agreement' is the wordplay.
'crowd' becomes 'press' (press is a kind of crowd).
'about' becomes 're' (regarding**).
'rental agreement' becomes 'lease' (I've seen this before).
'press'+'re'+'lease'='PRESS RELEASE'
'in' is the link.
(Other definitions for press release that I've seen before include "Notice for journalists" , "how to undo safety-belt?" , "Official statement to news media" , "Official announcement made to newspapers" , "Official statement issued to the media" .)
