Sorry I was in a bit of a rush earlier this morning and missed the obvious ...
The word "reporters" means "sounds like" in this arcane world of crosswords so ... "closely to follow"=HUGG + "a"="ER" + "criminal"=MUGGER. The result is HUGGER MUGGER (ie secret, secrecy and other meanings, although is usually hyphenated) but has nothing to do with journalists as I earlier wrote in error.
