The Election Commission on Thursday issued a show cause notice to Himanta Biswa Sarma asking the senior BJP leader for a reply on allegations levelled against him of threatening opposition leader Hagrama Mohilary of the Bodoland People's Front.

The EC issued the notice following a complaint filed by the Congress on March 30 alleging that Sarma had openly threatened to send Mohilary to jail by misusing the National Investigation Agency. The Congress and Bodoland People's Front are alliance partners in Assam.
