While Tse remained in Hong Kong, Luu began gathering gang members in New York in January 1989 in a retaliatory assassination attempt on the Ping On leaders in Boston. High-ranking Ping On members were aware of the plot, and Tse safely returned to the United States in May 1989 and October 1990 with Pham. The failed 1988 assassination attempt on Luu would lead to Tse's eventual conviction and incarceration: Tse was apprehended in January 1994 trying to cross the border from Hong Kong to China with $150,000; he was extradited to the United States and convicted in 1996 for attempted murder and conspiracy to commit murder, relating to the attempt on Luu and Meng in 1988.
