Police in India have arrested the social media head of one of the country’s main opposition parties over a doctored video of the interior minister.

The Congress Party’s Arun Reddy was detained on Friday, accused of being behind a widely-shared video showing Amit Shah promising to end support for millions of poor and under-privileged Indians.

The Congress says Mr Reddy was not involved, and accused the authorities of clamping down on rivals as the country votes in a national election.

The governing Bharatiya Janata Party (BJP) denies the charges.

Voting in India began on 19 April and has been staggered over several days until 1 June. The results will be announced on 4 June.

Mr Shah is often called India’s “second most powerful man” after Prime Minister Narendra Modi, and is seen as the mastermind behind the rise of the BJP.

The doctored video in question showed Mr Shah giving a campaign speech promising to end help for Muslims in the southern state of Telangana.
