Panaji (PTI): A siren giving a warning about tsunami erroneously started playing from the Early Warning Dissemination System at Porvorim near here, triggering panic among the local residents, an official said on Thursday.
The siren started sounding the alert after 9 pm on Wednesday and it continued for more than 20 minutes, local residents said.
Whether the siren went off due to any technical error or any other reason is being probed, with a state minister saying that he has sought a report into it.
The Early Warning Dissemination System (EWDS) is installed on a hillock at Porvorim in North Goa on the outskirts of state capital Panaji.
Talking to reporters on Thursday, North Goa District Collector Mamu Hage said, "It was a false warning as there was no such intimation of tsunami from any of the authorities."
"There was no mock drill or anything. I have personally checked and found out that there was no warning either from Indian Meteorological Department (IMD) or the Indian National Centre for Ocean Information Services (INCOIS)," she said.
The collector said she has directed the state Water Resources Department (WRD) to find out why the siren started playing from the EWDS.
People living in the nearby areas said the siren created panic among the locals.
Talking about it, local resident Avinash R said, "We were on a walk after dinner when we heard the siren. Initially we panicked, but we soon realised that it could be a mock drill."
When contacted, state WRD Minister Subhash Shirodkar said he has sought a report from his office, which will be received by this evening.
North Goa District Disaster Authority said in a social media post, "There are certain reports of Siren alerting Early Warning Dissemination System at Porvorim of a Tsunami alert. It is clarified that no such Alert of Tsunami is issued by the Indian National Centre for Ocean Information Services (INCOIS)."
"The citizens are requested not to panic," it added.

Mumbai/Kolkata/Silchar: A shocking incident aboard IndiGo flight 6E138 from Mumbai to Kolkata has gone viral, sparking outrage after a video emerged showing a man being slapped mid-flight while reportedly suffering a panic attack. The victim, identified as Hossain Ahmed Mazumdar from Assam, has since gone missing, and his family is seeking urgent answers.
The video, widely circulated on social media, shows Hossain in visible distress, attempting to leave his seat and reportedly requesting to deboard. As flight attendants tried to calm him down, another passenger suddenly approached and slapped him. The incident triggered immediate protest from fellow travellers.
A young man suffers a panic attack, his co passenger slaps him. Indigo airlines says “All appropriate regulatory agencies have been duly informed, in line with protocol.”

This is a criminal case and the man needs to be on a No Fly List @DGCAIndia pic.twitter.com/dY1gQC6ze0
Hossain, a gym trainer based in Mumbai, was en route to his hometown Katigorah in Cachar district via a connecting flight from Kolkata to Silchar. However, he never boarded the Silchar flight, and his mobile phone remains unreachable. His family, who had gathered at the Silchar airport, are now in distress. Zubairul Islam Mazumdar, a relative, said, “We have no idea where he is. We’ve contacted the police and airport authorities but haven’t received any concrete information.” His father, Abdul Mannan Mazumdar, who is undergoing cancer treatment, said tearfully, “He was our only hope. Now we don’t even know if he’s safe.” In a statement issued on August 1, IndiGo Airlines said: “We are aware of an incident involving a physical altercation on board one of our flights. Such unruly behaviour is completely unacceptable, and we strongly condemn any actions that compromise the safety and dignity of our passengers and crew. Our crew acted in accordance with established procedures. The individual identified as unruly was handed over to the security authorities upon arrival. Regulatory agencies have been informed as per protocol.”

However, the airline's statement has been criticised for failing to clarify what happened to Hossain after the incident, whether he received medical help, was detained, or was allowed to continue his journey.
Weak kneed response from @IndiGo6E . Has the man who got physical with a fellow passenger been put on a no-fly list? Has Indigo followed up on its complaint at point of disembarkation? If the passenger was handed over to the @CISFAirport were charges pressed? pic.twitter.com/qXMnfiBbFE

The video triggered widespread anger on social media, with many users interpreting the slap as a possible hate-driven act. However, aviation journalist Jagriti Chandra of The Hindu offered a clarification on X, stating: “The passenger who assaulted a co-passenger aboard IndiGo flight was handed over to law enforcement agencies for unruly conduct. Incident occurred after one passenger was feeling uncomfortable in the flight and wanted to deboard. Both belong to the same religious community.”

Despite this clarification, concerns remain about the airline's handling of a visibly distressed passenger, particularly in the context of mental health. Unverified posts circulating on social media claim that Hossain was later found, though there has been no official confirmation from authorities or the airline.
Alhamdulillah! Hussain Ahmed Mazumder, who was assaulted on an IndiGo flight while returning from Mumbai to Silchar and went missing, has now been found safe in Kolkata.
