Some harass us, pending arrest (7)
I believe the answer is:
suspend
'arrest' is the definition.
(both can mean to stop or cease)
'some harass us pending' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'SUSPEND' can be found hidden inside 'harass us pending'.
(Other definitions for suspend that I've seen before include "Stop for a time" , "Hang, defer" , "Stay" , "Adjourn" , "Hang - discontinue" .)
