In the first case, officials intercepted one passenger, who arrived at the airport in Shamshabad last night by a flight from Bangkok and quizzed him. It was found that he had concealed 2.36 kg gold worth Rs 80 lakh in an electronic instrument, a senior customs official said today.
The passenger belonged to Haryana and was subsequently arrested, the official said.
In another incident, officials last night recovered gold biscuits of 400 grams from a passenger, hidden inside his rectum.
