Wild otter grabbed the man in that place (7)
I believe the answer is:
thereto
'in that place' is the definition.
(I've seen this in another clue)
'wild otter grabbed the man' is the wordplay.
'wild' indicates anagramming the letters.
'grabbed' is an insertion indicator.
'the man' becomes 'he' (he refers to a man).
'otter' with letters rearranged gives 'treto'.
'treto' going around 'he' is 'THERETO'.
(Other definitions for thereto that I've seen before include "Up to that point" , "To that place" , "In addition" .)
