CHICAGO (AP) — A Taiwanese man who the U.S. government links to supplying weapons machinery to North Korea has been arrested along with his son.

The U.S. Attorney's Office in Chicago announced the arrests Monday. The men are accused of conspiring to thwart U.S. laws on the proliferation of weapons of mass destruction.

Prosecutors say the father, Hsien Tai Tsai, resides in Taiwan. He was arrested Wednesday in Tallinn, Estonia. The 67-year-old man remains in custody in the Baltic-coast country.

The son, Yueh-Hsun Tsai, is a legal permanent resident in the U.S. He was arrested the same day at his home in the Chicago suburb of Glenview. The 36-year-old was due to appear in federal court in Chicago on Monday.
