Intelligence agencies until last night, three days into the seizure of seven lakh Saudi rials equivalent to Tk 1.07 crore at Zia International Airport (ZIA), could not unearth any clue to the smugglers.

Customs intelligence found the rials Monday night abandoned in a black handbag onboard a Dubai-bound flight, No. 0025, of Biman Bangladesh Airlines. But they could trace neither the carrier nor the owner of the money.

A customs official yesterday filed a general diary with ZIA Police Station in this connection.
