On March 23, 2005 The Times of India reported, "Many Canadian Sikhs know who planted a bomb on Air-India's Kanishka aircraft 20 years ago, killing 329 people, but refuse to come forward for fear of terror reprisals, a Sikh community spokesman claimed. The admission follows last week's acquittal of two Sikhs accused of plotting the world's worst airborne terror strike prior to September 11, 2001. 'In our communities nobody will come forward, even though they know who did it, due to fear,' said Sadhu Singh Samra, vice-president of the Guru Nanak Sikh Gurdwara, North America's largest Sikh temple with 37,000 voting and 50,000 non-voting members."
