Entrap criminal, one with issue (6)
I believe the answer is:
parent
'one with issue' is the definition.
(issue can mean children)
'entrap criminal' is the wordplay.
'criminal' indicates an anagram.
'entrap' with letters rearranged gives 'PARENT'.
(Other definitions for parent that I've seen before include "Immediate ancestor" , "Begetter of offspring" , "Mother or father or what they do" , "Raise" , "person responsible for children" .)
