Police in southern India are investigating a senior leader of the country’s ruling Bharatiya Janata Party (BJP) over a political video targeting Muslims, as critics accuse Prime Minister Narendra Modi of running an increasingly divisive re-election campaign.

The police probe comes as the world’s most populous nation votes in a mammoth weeks-long election in which Modi’s Hindu-nationalist party is widely expected to secure a rare third consecutive term.

The party has long denied being anti-Islam but opposition politicians and prominent Muslims have warned that its leaders have been deploying openly divisive rhetoric to turbo-charge their campaign.

According to a police report seen by CNN on Tuesday, Karnataka state police are investigating whether local BJP leader B. Y. Vijayendra and the unnamed holder of the party’s official local X account “promoted enmity” between religious groups after the clip was posted online on May 4.

The 17-second animation depicts leaders of India’s main opposition Congress party giving benefits to Muslims, alongside a caption in the local Kannada language: “Beware… Beware… Beware…!”

It shows caricatures of Congress’s national leader Rahul Gandhi and its Karnataka Chief Minister Siddaramaiah feeding “funds” to a large bird wearing a Muslim skullcap, while giving nothing to three smaller birds portraying other marginalized minorities. The large bird then kicks the other birds out of their nest as the Congress politicians laugh.
