Unfortunately an edit brings arrest (6)
I believe the answer is:
detain
'arrest' is the definition.
(detain can mean to arrest or hold)
'unfortunately an edit' is the wordplay.
'unfortunately' indicates an anagram (a bad or unfortunate spelling).
'an'+'edit'='anedit'
'anedit' anagrammed gives 'DETAIN'.
'brings' acts as a link.
(Other definitions for detain that I've seen before include "Keep waiting or under restraint" , "Delay or take into custody" , "Keep back or arrest" , "Take into confinement" , "Hold or keep back, maybe for questioning" .)
