Timely sort of police raid (10)

I believe the answer is:

periodical

I'm a little stuck... Click here to teach me more about this clue!

'timely' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?

'sort of police raid' is the wordplay.
'sort of' is an anagram indicator.
'police'+'raid'='policeraid'
'policeraid' with letters rearranged gives 'PERIODICAL'.

Can you help me to learn more?

(Other definitions for periodical that I've seen before include "Newspaper" , "Magazine" , "Publication" .)

I've seen this clue in The Telegraph and The Globe and Mail.
