Hospital authorities said that unlike the bites suffered by revellers on the first day of immersion, the bites on the last day of Ganesh Chaturthi were not as serious and have been classified as “unknown fish bites”.

“The bites were mainly on the soles and the ankles and were not as serious as those seen on the first day of immersion. Those were said to bites of stingrays and jellyfish but this time the type of fish that has bitten people is yet to be identified. But there were no serious cases. All the twelve people were treated in the hospital. They were kept under observation for an hour or so and then were discharged as they were all stable,” said Dr Ramesh Bharmal, Medical Superintendent, Nair Hospital.
