Stopped working, dear, to take a break inside (8)
I believe the answer is:
Here is my best explanation:
'stopped' is the definition.
'working dear to take a break inside' is the subsidiary indication.
'working' is an anagram indicator.
'to take a break' becomes 'rest' (resting is a kind of taking a break).
'inside' means one lot of letters goes inside another.
'dear' with letters rearranged gives 'ared'.
'ared' going around 'rest' is 'arrested'.
(Other definitions for arrested that I've seen before include "Took into custody", "captured", "Taken into police custody", "Stopped or slowed down progress", "Stopped or slowed down development", "Taken into custody, being serrated", "Taken into custody or stopped", "stalled", "'Collared, nabbed, copped, (8)'" and "Detained by legal authority".)
