Parents abandon 11-year-old at Goa airport, leave for Dubai

"We are still waiting for a response. If they do not respond soon, we will decide on an alternative course of action," D'Souza told IANS.

What has exacerbated the problem is police inability to track down the boy's parents using the network of CCTV cameras installed in the airport premises.

With the help of the Central Industrial Security Force (CISF) and aided by Sameer, the police scanned nearly all the footage ranging from the time the boy claims he was dropped off till the flight to Dubai later in the afternoon.

"There is no track of his parents' names on flight manifests too. We expanded the CCTV search from the lobby to the security clearance and boarding area for the Dubai flight and later widened it to cover all other flights, but to no avail," an officer said.

Police are now in the process of checking hotel records and train departure lists to check if the couple is listed anywhere. A team is also expected to leave for Satara to verify the landmarks mentioned by the boy and scout for his address, even as Sameer continues to be shell-shocked and is being counselled.
