In view of the international ramifications and limitations on investigations by the state government on the matter, Kerala has asked the Centre to conduct a probe by the National Investigation Agency, Chennithala said in the assembly on a submission on the incident.
"On the basis of a report by DIG, state Home Secretary has written a letter yesterday to Union Home Secretary in this regard", he said.
The initial probe had found that of the 12 crew, seven were from Iran and five from Baluchistan, he said.
Pointing that the state viewed the presence of the dhow in its waters seriously in the wake of possibility of terrorist threats through the seas, he said there was no indication that the crew were engaged in fishing. "No fishing equipments like net or other materials were found in the dhow", Chennithala said.
