'The Bangladeshi national would then depart as a Bangladeshi passenger from the Delhi airport on the basis of genuine Bangladeshi passport carrying the forged Turkey visa. The forged Turkey visa would escape detection by Indian officials as genuine Bangladeshi passports were used,' he added.

Next, to avoid detection of the forged Turkish visa at the Istanbul airport, the Indian passport with the genuine Turkish visa but forged departure stamps was produced. 'At this stage, it was difficult for Turkish authorities to detect the fraud because the Bangladeshi national was using a genuine Indian passport with a genuine Turkish visa.'

Police said local agents in Turkey, also part of this racket, would now collect these passengers from the airports and send them to Greece either by road or by boat. As soon as the illegal immigrant got entry into Greece, he got a temporary visa on the basis of which he would start working there.

Thakur said Mohammad Jahinuddin alias Badul, a Bangladeshi national staying illegally in India, and Ali, who runs a travel agency Symphony Travels in Nizammudin area here, were the key accused in the case. Badul has been deported twice by Turkish authorities for trying to reach Greece, police said.

'Badul revealed during interrogation that he used to obtain Indian passports carrying genuine Turkey visas through a Mumbai resident named Vikram Sandhu. These passports were further forwarded to S.M. Ibrahim in Chennai for changing the photograph. Ibrahim has also been arrested,' Thakur added.
