The Election Commission had cancelled the bypoll yesterday.
On April 6, a replica of a coffin with late Chief Minister Jayalalithaa's figurine draped in national flag had been used by the AIADMK (Puratchi Thalaivi Amma) faction as part of the bypoll campaign, highlighting its demand for a probe into her death.
The 'coffin' was placed over the bonnet of an open jeep, with supporters of former Chief Minister O Panneerselvam seeking votes for their candidate E Madhusudanan.
The figurine of Jayalalithaa draped in national flag was a replica of the original and attracted attention.
An election officer had filed a complaint with the police alleging that Pandiarajan's action violated norms and disrespected the national flag, following which an FIR was registered.
