Taken into custody (8)
I believe the answer is:
arrested
'taken into custody' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for arrested that I've seen before include "on the way to . . . [PRISON] ?" , "'Collared, nabbed, copped, (8)'" , "Checked" , "Seized and took into custody" , "captured" .)
