Maharashtra Police, investigating the Maoist links to the Koregaon-Bhima violence, have stumbled upon letters that point to plans to assassinate Prime Minister Narendra Modi and Maharashtra Chief Minister Devendra Fadnavis, officials said in Pune today.

One of the letters has been found from the home of Delhi-based activist Rona Wilson, who was among the five persons arrested from different parts of India on Wednesday as part of the probe into the riots conspiracy and urban Maoist sympathisers.

The investigators said the communication seized from the laptop of one of the arrested persons says that Mr Modi has successfully established BJP government in more than 15 states and if this pace continues, then it would mean immense trouble for the Maoist party on all fronts.

Police said Maoists were thinking along the lines of “another Rajiv Gandhi-type incident” by “targeting Mr Modi roadshows” which they thought “could be an effective strategy”. The letter refers to a requirement of 8 crore rupees to procure M-4 rifles and 4 lakh rounds.

Former Prime Minister Gandhi was killed by an LTTE suicide bomber during his campaign for the May 1991 Lok Sabha elections in Sriperumbudur in Tamil Nadu. Pune Police has also released pictures of four more persons involved in January 1 violence that left one person dead and appealed to the public to inform them of their whereabouts.
