Wrecked and put in case on top of desk (10)

Ross

I believe the answer is:

vandalised

'wrecked' is the definition.

'and put in case on top of desk' is the wordplay.
'put in' means one lot of letters goes inside another.
'case' becomes 'valise' (valise is a kind of case**).
'on top of' says to take the initial letters (I've seen 'on top' mean this).
The initial letter of 'desk' is 'd'.
'and' put within 'valise' is 'vandalise'.
'vandalise'+'d'='VANDALISED'

(Another definition for vandalised that I've seen is " wantonly damaged".)

I've seen this clue in The Telegraph.
