Disha Ravi, 22, was arrested in Bengaluru on Saturday. Police said at a news conference on Monday that the document spread misinformation about the farmer protests on the outskirts of New Delhi and “tarnished the image of India.”

Police say Ravi shared the document with Swedish teenage climate activist Greta Thunberg, who tweeted it earlier this month.

They say the sharing of the document on social media indicated there was a “conspiracy” behind violence on Jan. 26, India’s Republic Day, when the largely peaceful farmer protests erupted into clashes with police. One protester died and hundreds of police and demonstrators were injured.

“The call was to wage economic, social, cultural and regional war against India,” police tweeted on Sunday.

Demonstrators Monday in the southern city of Bengaluru, including prominent historian Ramachandra Guha, held placards calling for Ravi’s immediate release. In the western city of Mumbai, around 50 people also demanded that Ravi be freed.

Her arrest has been condemned in India and beyond. Opposition parties called her arrest harassment, intimidation and an attack on democracy. Overseas, the niece of U.S. Vice President Kamala Harris, Meena Harris, criticized the government on Twitter for silencing activists.

Police also issued arrest warrants for two other activists, Nikita Jacob and Shantanu Muluk, saying the three created the document and shared it with others.

Police said the document contained links to websites that were pro-Khalistani, a movement for an independent Sikh homeland called Khalistan in the late 1980s and early 1990s. The government initially tried to discredit the protesting farmers, many of whom are Sikhs, as motivated by religious nationalism.

Since November, tens of thousands of farmers have camped outside the capital and blocked highways to protest new agricultural reform laws they say will devastate their incomes. The protests have posed a major challenge to Prime Minister Narendra Modi’s Hindu nationalist-led government, which says the laws are needed to modernize Indian farming.

Critics have accused the government of using the massive demonstrations to escalate a crackdown on free speech.

The protests attracted international attention earlier this month when pop star Rihanna, Thunberg and Meena Harris tweeted their support. India’s Ministry of External Affairs condemned “vested interest groups trying to enforce their agenda.”
