Shanmugalingam and three of his Indian associates were taken into custody based on an information that they were involved in trafficking Sri Lakan Tamils to Australia from the Prakasam coast, Prakasam district Superintendent of Police Ch Srikanth told PTI over phone.
"No one has been arrested and we are questioning the four," the SP said.
He said the modus operandi of the gang was to bring Sri Lankan Tamils to Chennai and then to Ongole in Prakasam district from where they used to take them in country boats in sea and later got them shifted into cargo ships heading towards Australia.
"It seems the gang members had collected Rs 5 lakh each from the victims under the pretext of providing them jobs in Australia," the SP said.
