Beijing/New Delhi/London: An Indian is among the 20 members of a tourist group whose excursion in China "went horribly wrong" when they were detained allegedly for having terror links and held incommunicado for almost two days, said a South African charity.

'Gift of the Givers Foundation' said in a Facebook post that the group was on a tour to explore ancient China as part of "a planned 47-day journey for 10 South Africans, nine Britons and one Indian national".
