A Trinity Problem

"One in three victims of domestic abuse in Britain", The Independent is reported to have said, "are male".
Are he, then ?  This is quoted by The Week.  Which of the two publications is responsible for the solecism ?  Both, perhaps.

Maybe we could say "One third of victims of domestic abuse in Britain are male", because although the victims, of either sex, are many, the term 'a third' is actually singular ('two thirds', of course, is (or are ?) obviously plural). But it is standard English usage to treat a singular collective noun (as with Manchester United or the Margate Town Council) as representing a group of plural people. Or other, non-human, animals. So the sentence 'A flock of geese were grazing on the common', or 'A group of children were playing in the street', or 'One third of domestic cats prefer Pussipaws' is (I mean, are all) acceptable.

"The trio was in fine form, weren't they ?" a member of the audience commented at the end of the concert. And the audience all applauded, it did. See ?
