Policeman getting information on weapon discovered in the centre of Bordeaux (8)
I believe the answer is:
gendarme
'policeman' is the definition.
(gendarme is a kind of policeman)
'information on weapon discovered in the centre of bordeaux' is the wordplay.
'information' becomes 'gen' (gen is a kind of information).
'on' means one lot of letters go next to another.
'weapon' becomes 'arm' (I've seen this before).
'discovered in' is an insertion indicator.
'the centre of' indicates the central letters.
The centre of 'bordeaux' is 'de'.
'arm' placed within 'de' is 'darme'.
'gen'+'darme'='GENDARME'
'getting' is the link.
(Other definitions for gendarme that I've seen before include "Soldier on police duty" , "Nice policeman" , "see in Paris!" , "Busy" , "Force man" .)
