SYDNEY: A former US Marine pilot fighting extradition from Australia on US charges of training Chinese military pilots to land on aircraft carriers, unknowingly worked with a Chinese hacker, his lawyer said.

Daniel Duggan, 55, a naturalised Australian citizen, feared requests by Western intelligence agencies for sensitive information were putting his family at risk, the lawyer said in a legal filing seen by Reuters. The lawyer’s filing supports Reuters reporting linking Duggan to convicted Chinese defence hacker Su Bin.
