Two Wiltshire men have been arrested on suspicion of robbery.
The arrests follow raids at William Hill in Corsham, and the Cheltenham and Gloucester in Devizes.
The pair, a 22-year-old man from Melksham, and an 18-year-old man from Chippenham, were arrested on suspicion of both robberies.
A Wiltshire Police spokesman said an imitation firearm had been recovered following property searches after the arrests.
He added the arrests came as a result of a tip-off from the public.
"Anyone who witnessed the William Hill robbery which happened just after 7.30pm on 23 February or the one at the Cheltenham and Gloucester bank on 9 March at 2.30pm is asked to ring police or Crimestoppers," he said.
