Police have already rounded up six persons and is maintaining vigilance on twelve others while probing various angles to crack the case, Capital Complex Superintendent of Police Hibu Tamang said.
"We have taken up the case as a challenge with all possible steps on to solve it at the earliest," Tamang said.
Arunachal Pradesh Chief Minister Nabam Tuki had yesterday said the case would be handed over to other premier investigating agencies if the state police failed to make a breakthrough.
Talking to reporters, he said no stone would be left unturned to nab the culprits who shot at Tongam Rina, the associate editor of Arunachal Times.
Tuki said he had already directed the police department to carry out an extensive inquiry, in a time bound manner, in order to catch the culprits.
Referring to previous attacks on media persons and media houses, including the April 15 vandalisation of Arunachal Times office, Hibu Tamang said, "Police being human beings cannot be expected to be omnipresent and omniscient."
"We seek the wholehearted willing cooperation of the civil society to crack the cases and also to maintain law and order to restore the confidence of the people," he said. (More)
