The Bengaluru unit of the Tax Intelligence Directorate recently submitted an investigation report to Bangalore Customs.
According to airport sources, agents attached to Customs in Bangalore who were stationed at the KIA cargo complex when the contraband offer came to light were suspended Thursday evening pending a ministerial investigation to determine their involvement.
On July 29, DRI detectives inspected a shipment for shipment to Dubai.
Although it was declared as plastic pipes used in building construction, the shipment contained red sanders weighing over three tons and valued at over Rs 6 crore in the international market.
Chopping or large-scale trading in red sanders, a rare wood, is prohibited by Indian law.
The DRI team carried out an investigation.
The three officers were suspended after the report was submitted, airport sources said.
However, the identity of the officers was not disclosed as Bangalore Customs are conducting an internal investigation into the red sanders case themselves, sources added.
