Delhi's Chief Minister Arvind Kejriwal said that his office had been raided by federal investigators on Tuesday, accusing Prime Minister Narendra Modi of waging a political vendetta against his administration.

"CBI (Central Bureau of Investigation) raids my office," Kejriwal, who is the leader of an anti-corruption party, said on Twitter.

"When Modi (could not) handle me politically, he resorts to this cowardice."
