Reassembly of features page recently stolen from computer department (8)
I believe the answer is:
photofit
'reassembly of features' is the definition.
The definition suggests a singular noun which matches the answer.
'page recently stolen from computer department' is the wordplay.
'page' becomes 'p'.
'recently stolen' becomes 'hot' (I've seen this before).
'from' says to put letters next to each other.
'computer department' becomes 'ofit' (I can't justify this - if you can you should give a lot more credence to this answer).
'p'+'hot'+'ofit'='PHOTOFIT'
Can you help me to learn more?
(Other definitions for photofit that I've seen before include "match perhaps" , "identification of suspect" , "Impression of police suspect" , "Police hunt picture" , "Help for witness" .)
