Sniffer dogs have helped to uncover thousands of illegal cigarettes in Great Yarmouth.
More than 27,000 illegal cigarettes and nearly 6kg of illegal hand rolling tobacco were seized from the two stores.
Thursday's raids were carried out by Norfolk County Council Trading Standards together with Norfolk Police and Environmental Health.
During one, a sniffer dog uncovered a secret door which led to a concealed stash behind a water heater.
All the businesses were visited as a result of intelligence received from members of the public and police.
