After studying speeches of Dr Zakir Naik, Intelligence Dept gives him clean chit

Bengaluru, May 20: A mysterious "boom" heard in large parts of Bengaluru this afternoon left residents of the city and social media users puzzled. While the source of the sound is being investigated, the Indian Air Force (IAF) indicated that it could be the result of "routine test flights that necessitate going supersonic a times".

The sound was heard from as far as the Bengaluru airport in Devanahalli to the IT hub of Electronic City 54 km away. It was also heard in Kalyan Nagar in east Bengaluru, central Bengaluru's MG Road and areas such as Marathahalli, Whitefield, Sarjapur and Hebbagodi.

IAF said no aircraft of training command was flying in the area. "However, ASTE (Aircraft and Systems Testing Establishment) and HAL (Hindustan Aeronautics Limited) could have been undertaking their routine test flying, which necessitates going supersonic at times. These are done well beyond the city limits in specified sectors. However, considering the atmospheric conditions and reduced noise levels in the city during these times, the aircraft sound may become clearly audible even if it happened way out from the city," said the air force statement.

Many people had speculated that the sound could have been caused by a fighter jet such as a Mirage 2000.

"We have also asked the Air Force Control Room to check if it was a jet or supersonic sound. Bengaluru police are awaiting confirmation from the Air Force," Bengaluru police commissioner Bhaskar Rao said in a statement.

It was not an earthquake, Karnataka's state disaster monitoring centre had tweeted earlier.

"Earthquake activity will not be restricted to one area and will be widespread. We have checked our sensors and there is no earthquake activity recorded today," the Karnataka State Natural Disaster Monitoring Centre said, quoting its director Srinivas Reddy.

"The activity reported in Bengaluru is not due to an earthquake. The seismometers did not capture any ground vibration as generally happens during a mild Tremor. The activity is purely a loud unknown noise," the agency tweeted.

#Bangalore and #BangaloreBoom was among the top trends on Twitter this afternoon.

"We are trying to ascertain the source of the noise," a senior police officer said. "In Whitefield area, we have searched on the ground and so far, there is no damage to any property," he added. There were no calls to the police control room reporting any damage.

New Delhi, Mar 29: "What corona? My children are hungry, they have walked from Gurugram with me do you think corona is what I fear?," Yogesh Gangwar who is salesman in a cloth showroom said as he wiped his tears.

Many others regret for not leaving the city early on.

"God knows when we will reach our hometown. My family was telling me to leave work early in March and get back, but I avoided suggestions and now I am stranded here," Babu Ram who hails from Rampur and works at a plastic recycling factory here in Mundka told media.

Migrant labourers were forced to walk as the public transport were closed and borders were sealed due to the lockdown.

"There is no food to eat, I cannot pay rent of room without my daily wages so I decided to walk with my family from Narela to here. I just hope I get a bus soon," Revati, who works as construction labour said as she fed her three-year-old with pieces of bread that one of the policemen at Anand Vihar gave her.

However, when Yogi Adityanath-led BJP government in Uttar Pradesh decided to deploy around 1,000 buses to help these workers reach their respective hometowns, thousands of them reached Anand Vihar ISBT with a hope to catch one of these buses.

The Delhi government also announced that 100 buses have been deployed to help those trying to reach to their homes in other states on foot.

In order to avoid the spread of the virus, the police asked the people to stand in three queues and also asked the people to de-board the overcrowded buses.

Earlier, budget passenger carrier SpiceJet had offered its aircraft to operate few flights from Delhi and Mumbai to Patna to take migrant labourers, particularly from Bihar, who have got stuck in various parts of the country due to COVID-19 related lockdown.
