One’s to arrest Tory sex symbols (5)
I believe the answer is:
icons
'sex symbols' is the definition.
'icons' can be an answer for 'symbols' (I've seen this in another clue). I am not sure about the 'sex' bit.
'one's to arrest tory' is the wordplay.
'one's' becomes 'I's' (Roman numeral).
'to arrest' indicates putting letters inside (inserted letters are arrested or held).
'tory' becomes 'con' (abbreviation for conservative).
'is' placed around 'con' is 'ICONS'.
Can you help me to learn more?
(Other definitions for icons that I've seen before include "Graphic symbols on computer screens" , "Religious or computer images" , "Religious pictures" , "Images or statues, or computer screen symbols" , "Sacred paintings or computer screen symbols" .)
