Based on a tip-off, Directorate of Revenue Intelligence officials took into custody for questioning Abdul Gaffoor Nasroon and Mohammad Zainul Hussain -- both natives of Kerala, who arrived here by a flight from Dubai around 5.30 AM.
Investigations revealed that they had hidden the gold biscuits in the lavatory of the plane, in which they travelled from Dubai and two accomplices-- Mohammad Yousuf Abdul and Mohammad Yasin Abdul Hussain-- who were waiting to board the same flight on its second leg to Delhi, supposed to pick them up.
