Thiruvananthapuram: In another twist to the Thiruvananthapuram gold smuggling case, gunman of United Arab Emirates’ (UAE’s) consular attaché has been missing for the last two days.

Gunman Jaya Ghosh's kin allege that Ghosh received several threat calls around the same time as smugglers suspect he was the one who tipped off the Customs department about the attempt to smuggle gold.

Relatives suspect he may have been taken into custody by the NIA, but the agency refuted the claim. Before Ghosh went missing, he had surrendered his service pistol, his brother-in-law said.

Attaché Rashid Khamis Al Ashmiya left the country three days ago as the investigation into the case progressed.

The bag containing the gold, which Swapna Suresh and Sarith allegedly tried to smuggle, was in the name of the attaché at the UAE Consulate. It is also reported that the attaché had attempted to ensure that diplomatic baggage was not opened by officials.
