Motorists following as escorts creating disturbance (6)
I believe the answer is:
fracas
'disturbance' is the definition.
(I've seen this before)
'motorists following as escorts' is the wordplay.
'motorists' becomes 'rac' (short for Royal Automobile Club).
'following' becomes 'f.' (used when citing page numbers etc).
'escorts' indicates putting letters inside (inserted letters are carried or escorted by others).
'f'+'as'='fas'
'rac' inserted within 'fas' is 'FRACAS'.
'creating' is the link.
(Other definitions for fracas that I've seen before include "Noisy altercation" , "Bust-up" , "Dust-up" , "Noisy brawl" , "Affray" .)
