Rang Ted about police search? (7)
I believe the answer is:
dragnet
'police search?' is the definition.
(I've seen this before)
'rang ted about' is the wordplay.
'about' indicates an anagram.
'rang'+'ted'='rangted'
'rangted' with letters rearranged gives 'DRAGNET'.
(Other definitions for dragnet that I've seen before include "Mesh drawn across river to catch fish" , "Intense police search for suspect" , "Granted (anag.); police search" , "Seabed trawl" , "Systematic search (for criminals)" .)
