"In the Assembly constituency, there are totally 230 polling stations in 49 locations. Out of them, 22 polling stations in 15 locations have been identified as vulnerable on various counts", state Chief Electoral Officer Sandeep Saxena said in a press release today.
The constituency is going for by-election on June 27 with Jayalalithaa and CPI nominee C Mahendran being the key contestants.
"Police patrolling being done in these areas. Extra SVEEP (Systematic Voters' Education and Electoral Participation) activities for awareness creation would be undertaken. A picket will be posted on poll day and micro observers will be closely watching the poll process", he said.
Of the ten companies of CAPF requisitioned, four companies of Border Security Force personnel and one from Central Reserve Police Force have been deployed for poll related duties from June 18, he said adding the remaining personnel would be deployed from June 23.
Jayalalithaa was sworn in Chief Minister on May 23. She was earlier disqualified as MLA of Srirangam on being convicted in the assets case by a Bengaluru trial court in September 2014.
Opposition DMK, BJP, Congress, MDMK and PMK have announced boycott of the election largely alleging that the ruling party would use "money power".
