The Lok Sabha on Tuesday paid homage to Jharkhand Mukti Morcha member Sunil Kumar Mahato, who Naxalites killed on Sunday.

Speaker Somnath Chatterjee said the dastardly crime had seriously affected proper functioning of country's democratic institutions and created insecurity.

The House stood in silence for a minute as a mark of respect to Mahato after which it was adjourned for the day.

"The tragic assassination of Mahato is being and should be condemned by all sections of the people," Chatterjee said.

He said: "A life of promise of a Member of Parliament has been extinguished by senseless violence, seriously affecting the proper functioning of our democratic institutions and also creating insecurity and law and order problems."

Mahato, who represented Jamshedpur constituency in the Lok Sabha, was gunned down when he was attending a sports event in his constituency at Baguria in East Singhbhum district of Jharkhand.

Describing Mahato as a dedicated social and active political worker, Chatterjee said the late MP had worked tirelessly for the uplift of the tribal people.

Through his interventions in the House, he vigorously championed the cause of the tribal people and other deprived sections of society, the speaker said.
