Pratap Reddy, a retired official of the forest department, succumbed to his injuries at a private hospital Saturday, a day after he was injured in the incident that took place at Vanasthalipuram in the limits of Cyberabad police commissionerate.

A traffic sub-inspector flung his lathi in an effort to stop a speeding biker but it hit the old man who sustained head injuries. He was taken to the hospital in a critical condition.
