Radical preacher Amritpal Singh, who is on the run following a police crackdown, has been maintaining close links with Pakistani intelligence agency Inter-Services Intelligence (ISI) and some terrorist groups based abroad, official sources said on Saturday.
Sikh Federation UK, which has styled itself as one of the largest Sikh organisations based in the UK, said Avtar Singh was terminally ill with blood cancer. He was on a life support system for the last few days.
The fringe organisation, run by a few radical Sikhs of foreign nationality in the US, Canada, the United Kingdom openly espouses the cause of Khalistan and in that process challenges the sovereignty and territorial integrity of India.
The home ministry can notify Google of the Voice of Punjab app's hateful content and have the app taken down from the app store. The glorification of Beant Singh's assassination alone is enough to have the app taken down.
Amritpal Singh and others are on the run and a massive manhunt has been launched to nab them, a police spokesperson said.
Prime Minister Narendra Modi is likely to ask Britain to take strong action against Sikh groups trying to revive the demand for a separate Khalistan and their attempts to radicalise Sikh youth besides giving them training on how to make bombs.
