Two men have been arrested after drugs with an estimated street value of nearly £800,000 were recovered by police.
Officers netted the drugs, believed to be heroin, after searching a number of properties in the Bellsmyre area of Dumbarton yesterday.
Police Scotland said two men, aged 27 and 34, have been arrested and were being held in police custody. They were expected to appear at Dumbarton Sheriff Court.
A report will be sent to the procurator fiscal.
