New Delhi: Bharatiya Janata Party (BJP) MP Subramanian Swamy said on Friday that he has spoken to National Security Adviser Ajit Doval over the news regarding the Prime Minister Narendra Modi's assassination plot and said the matter must not be taken lightly.

Swamy made the comments after the Pune Police revealed that they have intercepted an internal communication of the Maoists plotting to kill Prime Minister Modi in 'Rajiv Gandhi-Type' assassination.

Swamy told ANI, "I called up National Security Adviser Ajit Doval and spoke to him regarding this matter. I'll be writing a letter to him on Monday. Since the Congress party is also involved or has been named, this shouldn't be taken lightly. There is no doubt that PM Modi has been our star campaigner and has influenced our performance."

He also urged all investigative agencies to take note of the matter and deal it at the highest level.

Reacting to the remark made by Congress leader Sanjay Nirupam, who called it "planted" information, Swamy slammed the grand old party for saying such "untested things".

On Thursday, the Pune police told a court that they were in possession of a letter, seized from the residence of one of the five people, who have been arrested in connection with the Bhima-Koregaon violence, which talks about the assassination of Prime Minister Modi in Rajiv Gandhi-type incident.
