A Canadian judge has acquitted two Canadian Sikhs of charges related to the 1985 downing of an Air India plane and bombing at a Tokyo airport that killed 331 people. The judge, Bruce Ian Josephson said witnesses in the nearly two-year long trial were not credible. Prosecutors had said Ripudaman Singh Malik and Ajaib Singh Bagri were guilty of plotting the two bomb attacks to get revenge for an Indian army attack on the Sikh Golden Temple at Amritsar. The first bomb killed two baggage handlers at Tokyo's Narita airport on June 23rd, 1985. The second bomb destroyed Air India Flight 182 off the coast of Ireland, killing all 329 people on board. Ahead of the trial, a third suspect plead guilty to lesser charges and the alleged mastermind of the plot died in a police shootout in 1992.
