It came to light on Monday morning when visitors to the Corporation office panicked after noticing blood stains and signs of other rituals at many places — from the entrance to the payment counters to other offices on the premises.

It was suspected that animal sacrifice was performed and blood sprinkled around the premises.

The public, who were initially scared, cornered the minicipal officials and asked how they could have allow the performance of such bizarre rituals inside a government office.

For their part, Corporation officials too were initially clueless. Later they claimed that a yagna was performed on Sunday night as many staff and councillors were falling sick frequently.

So, who organised the yagna? There were no answers.

When contacted, Mayor J Rekha Priyadharshini said she did not attend office for a week and was not in anyway connected with the yagna.

According to her, the building contractor, who had undertaken a job inside the Corporation premises, could have performed it because his workers were meeting with accidents frequently while at work.

The mayor had no idea why blood stains and other signs were found at many places on the premises instead of being confined to the work site.
