A man, who came to cast his vote during polling on May 10 and instead damaged the EVM control unit in Mysuru, is suspected by the police to be mentally unsound.
The incident came to light after a delay when videos of a man grabbing the EVM control unit and banging it on the ground went viral on Friday.
The authorities identified the man as Shivamurthy, 48, and said the incident took place in a polling booth in Hootagalli coming under Chamundeshwari Assembly constituency.
