Wuthikorn Naruenartwanich, alias Willy Naru, was arrested in August, 2013 on India's request for allegedly brokering arms deals between Chinese suppliers and Anthony Shimray, a top operative of the Nationalist Socialist Council of Nagaland (Isac-Muivah) or NSCN-IM faction.
Shimray, who was arrested on Indo-Nepal border in October 2010, had indicated that Willy had helped him to purchase weapons and ammunitions worth USD 1.2 million.
Indian intelligence traced their contact and found that they had made the deal via email and an amount of USD 8,00,000 had already been paid.
"The court said he should be extradited within 90 days but we hope to do so in a month," sources told PTI.
