A Danish man who has admitted parachuting arms into the Indian state of West Bengal in 1995 has been arrested after officials in Denmark agreed to back his extradition, authorities have said.
A prosecutor said police had long known that Niels Holcks, 47, was in Denmark, but negotiations over his possible extradition had dragged on for years.
"It is correct that we have had knowledge of Niels Holcks's whereabouts in Denmark since 2001," Birgitte Bundsgaard said yesterday.
"The reason why the ministry of justice decided to arrest him today is partly that it has taken several years to negotiate the terms for a potential extradition with Indian authorities."
Holcks has admitted parachuting four tonnes of arms into West Bengal along with five Russians and a Briton to help locals in their fight against the government.
Denmark has received assurances that Holcks will not be sentenced to death and that he will be sent back to the Nordic country to serve any possible sentence, according to Danish news agency Ritzau.
He will appear before a judge today.
Holcks wrote an autobiography two years ago titled "They Call Me Terrorist" and which recounts delivering the arms during a flight that left from Bulgaria, with Thailand as a final destination.
India's air force intercepted the plane on the return flight, but Holcks managed to escape, unlike the others.
