Hari Om, the bodyguard of farmer leader Manvir Singh Tevatia, was allegedly killed in "a rehearsal firing" by farmers on Friday.
Tevatia, however, claimed that some unknown persons had come to the village and fired at farmers, in which Hari Om died.
The deceased was accused in an extortion case in the Rabupura police station, Greater Noida.
"The police recovered his body from a car. Farmers were taking him to a hospital when they saw a PCR van near Gautam Budha University. They abandoned him in the car and fled. A police team took the injured to the hospital, where he was declared brought dead," said Rakesh Jolly, SP (Greater Noida)
Some farmers claimed that there was a difference of opinion over keeping the three Uttar Pradesh roadways staff hostage. Some wanted to end the agitation and release them without any condition. They were in favour of holding talks with the state government to solve the land acquisition problem.
"The other group was against releasing the roadways staff and favoured violence. They had called some youths from nearby villages and were imparting training to them, when a bullet hit Hari Om," said Vishal Singh, sub-divisional magistrate.
