Christian apprehended, so we hear (4)
I believe the answer is:
copt
'christian' is the definition.
(member of the Coptic Church, a Christian church)
'apprehended so we hear' is the wordplay.
'apprehended' becomes 'copped' ('cop' can be a synonym of 'apprehend').
'so we hear' indicates a 'sounds like' (homophone) clue.
'copped' is a homophone of 'COPT'.
(Other definitions for copt that I've seen before include "Member of ancient Egyptian church" , "Egyptian Christian Church member" , "Christian in mainly Moslem country" , "Early Christian" .)
