Leave to avoid arrest (7)
I believe the answer is:
abscond
'leave to avoid arrest' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for abscond that I've seen before include "Flee" , "Steal away" , "Leave hurriedly (to avoid arrest)" , "Go away secretly after wrongdoing" , "Leave quickly to avoid punishment" .)
