Weight-lifter caught drug smuggling legged it (5)
I believe the answer is:
crane
'weight-lifter' is the definition.
(I've seen this in another clue)
'caught drug smuggling legged it' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'drug' becomes 'e' (E is another name for ecstasy).
'smuggling' is an insertion indicator (some letters smuggled inside).
'legged it' becomes 'ran' (I've seen this in another clue).
'c'+'e'='ce'
'ce' going around 'ran' is 'CRANE'.
(Other definitions for crane that I've seen before include "Wading bird to lift heavy objects?" , "Lifting machine or long-legged bird" , "Stretch out (one's neck)" , "Tall wading bird can lift heavy loads" , "To do it could mean a long stretch" .)
