Do search in the centre with others (6)
I believe the answer is:
arrest
'do' is the definition.
(do can mean arrest as in 'got done')
'search in the centre with others' is the wordplay.
'in the centre' says to take the centre.
'with' means one lot of letters go next to another.
'others' becomes 'rest' (I've seen this before).
The centre of 'search' is 'ar'.
'ar'+'rest'='ARREST'
(Other definitions for arrest that I've seen before include "Bring to a standstill" , "Sartre (anag) -- check" , "Nab" , "Catch" , "Stop - detain" .)
