U.S. prosecutors have indicted a Taiwanese father and son on charges related to the supply of machinery to North Korea that could be used in the production of weapons of mass destruction.

Hsien Tai “Alex” Tsai, 67, and his son, Yueh Hsun “Gary” Tsai, 36, were charged during a Monday afternoon hearing at federal court in Chicago. Both were arrested last week.

Alex Tsai was picked up in Estonia, where he remains in custody awaiting extradition to the U.S., and Gary Tsai was arrested at his home in Glenview, Illinios. Gary Tsai is a legal permanent resident of the U.S.
