With the venue being on the Western Ghats and also close to the mountain ranges in Kerala, additional police personnel would be deployed along the state borders to prevent possible infiltration of extremists and Naxalites, police said.
The tight security was also being put in place in view of planned protests by human rights organisations, various political parties, farmers and tribal bodies, alleging that Adiyogi's face was built on encroached land and that Modi's visit would only regularise it (land).
Modi is scheduled to arrive by 5.30 PM at Sulur airport near here and then leave for the venue by a helicopter.
