A delegation of Congress party led by former Raipur Mayor Kiryanmayee Nayak registered a series of complaints on Saturday with office of Chhattisgarh Chief Electoral Officer while raising the point that they suspect, the EVMs would be hacked.
The delegation members demanded that signal jammer should be installed in all the strong rooms across the state.
Through a letter, the party leaders pointed out that they have received information that hackers have been called from outside.
The letter sought to make arrangement for stay of the Congress candidate for monitoring near the strong room and granting permission for it.
The delegation also handed over a letter for re-polling in selected polling booths mainly at Kondagaon.
