Chandigarh/IBNS: A police officer was injured Friday in a clash between protesting farmers and cops in Khedi Chwpata in Haryana's Hisar. 

Visuals showed a chaotic and volatile situation as police, escorted by riot personnel in full gear, can be seen taking people into custody while farmers surrounded them.

Tear gas shells were fired and police resorted to a lathi charge as farmers threw stones at them.

The violence broke out as the farmers were stopped from marching to Khanauri on the Punjab border.

The farmers were headed to join thousands of others who have gathered there, and at the Shambhu border crossing, ahead of a 'Delhi Chalo' march to demand a legal guarantee for MSP, or minimum support price, and waiver of farm loans, pensions, and rollback of increased electricity rates, among other things.

Earlier in the day, a 62-year-old farmer died in Khanauri after suffering a cardiac arrest.

Darshan Singh was from Punjab's Bathinda district and was the second person to have died in these protests.

On Wednesday Subhkaran Singh, 21, died during a clash with the cops.

Singh died after farmers rushed barricades set up by the police at the Khanauri border crossing to stop them from reaching Delhi.  A delayed postmortem showed a head injury.

Farmer leaders said his body would not be cremated till the Punjab government registered a case against the person responsible.

Chief Minister Bhagwant Mann, who expressed sorrow over Subhkaran Singh's death, said a case would be filed after the post-mortem.

"Those responsible will have to face stringent action," the Aam Aadmi Party leader said, as he announced Rs. 1 crore compensation and employment for Singh's sister.
