Bad cut ruptured in hijack (6)
I believe the answer is:
abduct
'hijack' is the definition.
(I've seen this before)
'bad cut ruptured' is the wordplay.
'ruptured' is an anagram indicator.
'bad'+'cut'='badcut'
'badcut' with letters rearranged gives 'ABDUCT'.
'in' is the link.
(Other definitions for abduct that I've seen before include "Snatch away" , "Take (someone) away by force" , "Hijack" , "Kidnap, make off with" , "Criminally remove to an undisclosed location" .)
