Indian Airlines — Flight IC423

Indian Airlines Flight 423 was hijacked by five Sikh militants of the Dal Khalsa organization while en route from Delhi to Amritsar. The hijackers, armed with daggers and a hand grenade, forced the Boeing 737 to land at Lahore Airport in Pakistan. They demanded the release of militant leader Jarnail Singh Bhindranwale and 500,000 USD in cash. Following a request from the Indian government, Pakistani Special Service Group (SSG) commandos stormed the aircraft on September 30, 1981, successfully apprehending the hijackers and releasing all 111 passengers and 6 crew members without fatalities.

Report

Investigation Summary

The hijacking was led by Gajender Singh, co-founder of the Dal Khalsa, who communicated his demands to Natwar Singh, India's ambassador in Pakistan. The militants sought the establishment of a separate Sikh homeland, Khalistan, and the release of several prisoners, including Jarnail Singh Bhindranwale. The standoff lasted into the following day at Lahore Airport. During the negotiations, the hijackers released 46 of the 117 people on board. The resolution involved a tactical intervention by Pakistan's elite Special Service Group (SSG), who launched an assault to clear the aircraft while 71 people (65 passengers and 6 crew members) remained on board. The five hijackers were captured and subsequently tried in Pakistan, where they received life sentences. One of the hijackers, Satnam Singh, returned to India in 1999 after serving his sentence and faced further legal proceedings, though he was eventually discharged by an Indian court on the grounds of double jeopardy. Gajender Singh remained in exile in Pakistan until his death in 2024.

Final Conclusions

The incident concluded with a successful commando operation by the Pakistani military. All hostages were rescued unharmed. The hijackers were convicted and sentenced to life imprisonment in Pakistan. Legal proceedings in India decades later regarding the same individuals were largely dismissed because the suspects had already served their sentences for the crime in Pakistan.
