Ten thousands illegal cigarettes were seized by police and trading standards from a city centre shop.
They were found in a secret cupboard concealed in the floor of War Sawa, on Kirkgate.
The joint operation was carried out by the Central neighbourhood police team and West Yorkshire Trading Standards on Tuesday after a tip off from the community.
Sgt Bob King said: “The cigarettes seized were suspected of being illegal with no duty paid on them or fakes.
“In addition to other licensing offences were also discovered. The owner of the shop will be interviewed by officers under caution next week.
“And further checks will be carried out on other shops in the Kirkgate area in future.”
Anyone with information should call police on 101.
