Press articles on country arrest­ing a small number (3,6,6)

'press' is the definition.
(informal term for the media or press)

'articles on country arresting a small number' is the wordplay.
I cannot quite understand how this works, but
'articles' could be 'tat' (I have seen 'Tawdry articles' mean 'tat' so perhaps 'articles' could also mean 'tat') and 'tat' is located in the answer.
'on' could be 'o' (I've seen this in other clues) and 'o' is found within the answer.
'small' could be 's' (abbreviation - e.g. clothes size) and 's' is located in the answer.
'number' could be 'e' (e is a kind of number) and 'e' is found in the answer.
This explanation may well be incorrect...
