Ok, providing a little context here about how this played out.
1. A group of Hindu women petition a court for the right to (continue) worship at (what is now) the Gyanvapi mosque
2. The court orders that a survey of the mosque be carried out to determine if there is a historical locus standii for the petition
3. Videos of the survey reveal what appears to be a Shiva linga in a pond used for ablutions
4. Heated TV debates on prime time about the find. In one such debate a muslim cleric makes derogatory references to Shiva. In response a spokesperson of the ruling BJP, Nupur Sharma, says Prophet Mohammed married a girl of 6 and consumated the relationship when she was 9.
5. Zubair Mohammed of Altnews, begins a tweetstorm against Nupur Sharma and the channel for hurting muslim sentiments by making derogatory references to the prophet
6. Nupur Sharma says she is receiving threats due to Zubair's call and goes into hiding. Police on the lookout to arrest her for offending religious sentiments
7. Several videos posted demanding that she be killed and processions with "Sar tan se juda" slogans taken out (separate head from body)
8. Several also post "IStandWithNupur" in her support on social media. One such person is a tailor named Khanaiyya in Udaipur.
9. Khanaiyya is beheaded for standing in support of Nupur Sharma. The murderers record the killing on video and also threaten that the prime minister will meet the same fate
10. Many see this as a result of Zubair's call for action against Nupur and pull up old tweets of his with derogatory comments against Hindu practices demanding his arrest
11. Zubair is arrested and Altnews financials come under the scanner. Police use section 91 to obtain details of Altnews financing via Razorpay
