Indian students angered by Thunberg ally's arrest

Protests in India over the arrest of an environmental activist with ties to Greta Thunberg are now widening to include student groups.

Disha Ravi is the leader of the local arm of Thunberg's advocacy group and is accused of sedition.

Police say she created and shared an online "toolkit", used to stir violence in Delhi last month during the ongoing farmers' protests.

Her supporters say she was just providing an information pack about the protests, which erupted late last year over agricultural reforms.

[Protester and member of India Students Association Kamal Preet Kaur, saying:] "We still live in a democracy…there are democratic procedures in a democracy that the police have to follow. And I want to ask a simple question, that if someone raises his voice if someone writes in favour of the farmers, on which grounds does he becomes a traitor?"

Ravi's arrest comes at a time when the government faces allegations that it is suppressing dissent - a charge it denies.

Police said Ravi's detention was part of an investigation into the violence that took place on January 26.

Thousands of farmers tore down barricades in Delhi on India's Republic Day, storming the historic Red Fort and raising religious flags.

Meanwhile, the farmers protests continue, with thousands camping on the outskirts of the capital.
