The bypoll slated for April 12 was cancelled subsequently following allegations of large-scale distribution of money to voters, entailing raids by the tax authorities.
The ECI said it had directed the CEO, Tamil Nadu on April 18 to ask the RK Nagar returning officer to file a complaint with police for bribing the voters.
In its response to a plea under Right to Information Act by a Chennai-based lawyer, M P Vairakkannan, a copy of which was circulated to media here, ECI Secretary Malay Mallick in his letter to the CEO refers to the Income Tax report on raids in Tamil Nadu, vis-a-vis the bypoll.
The letter said the Commission had received a report on April 9 from IT department on search and seizure of documents indicating large-scale distribution of money to bribe voters.
The alleged bribe/ inducement was to influence the bypoll in RK Nagar which is an offence under IPC, the letter noted.
"Considering the facts and circumstances of the case, the Commission has directed that an FIR may be filed by the RO in the instant case," the letter said.
The RTI plea of April 26 was received by the Commission on May 3 and the first of its eight questions sought to know about the action over the alleged distribution of money.
The query asked as to what action the poll panel would be taking against the electoral misconduct of distribution of money to voters in RK Nagar constituency against various persons.
The people against whom the proposed action by the poll panel had been enquired about included AIADMK (Amma) deputy general secretary T T V Dhinakaran, Chief Minister Edapadi K Palanisamy and ministers Sengotaiyan, Sellur K Raju, Thangamani and Vijayabaskar.
