People took to the streets of Karnataka on Tuesday and called for hartal in Kolar district of Karnataka, following the death of Indian Administrative Service (IAS) officer D K Ravi, who took on the real estate mafia and 'exposed tax frauds', reports the Times of India.

Huge crowds had gathered outside Ravi's residence to pay tributes and accompany the IAS officer's body on his final journey.

There were also protests in different parts of the town with protesters demanding an independent probe into the case. The protests were marked by stray incidents of stone pelting. ​

Angry protesters in Kolar district also blocked a national highway placing burning tyres before being chased away by police.

The house of local MLA in Kolar Varthur Prakash was stoned but police rushed and dispersed the protesters, police said.

Exams in the state had also been postponed.
