Obsessively indecent type produces pressure on Russia to find individual in Split (8)
I believe the answer is:
prurient
'obsessively indecent' is the definition.
'prurient' can be an answer for 'indecent' (thesaurus). I am not sure about the 'obsessively' bit.
'type produces pressure on russia to find individual in split' is the wordplay.
I cannot quite understand how this works, but
'pressure' could be 'p' (abbreviation) and 'p' is found in the answer.
'individual' could be 'i' and 'i' is located in the answer.
'on' could be 're' ('on' can be mean 'with reference to') and 're' is found within the remaining letters.
The remaining letters 'runt' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for prurient that I've seen before include "Turn ripe (anag) - lewd" , "Encouraging lustfulness" , "rather too interested in sex" , "nastily obsessive" , "Unhealthily interested in sexual matters" .)
