Around 50,000 illegal cigarettes were found during raids at shops across Glasgow.
A tobacco detection dog helped trading standards officers during searches at four businesses in Govanhill.
The premises were visited as part of Operation CeCe Scotland, a joint initiative between Scottish Trading Standards Services and HMRC to tackle the illegal tobacco trade at the retail level.
A spokesperson for Glasgow City Council said: “Boo is trained to sniff out tobacco that’s been purposefully hidden in locations which would not have been apparent during a routine inspection allowing officers to find potentially dangerous and harmful products.”
