Indrajit, who had threatened Gauri Lankesh, not cooperating in probe: SIT

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.

Bengaluru, Jan 30: A kidnap case in Bengaluru has proved that crime-based series on TV channels can inspire youth to commit crimes. 21-year-old Chirag R Mehta, who kidnapped a schoolboy and got arrested within an hour after demanding Rs 5 lakh ransom, has told police that he thought of abducting the boy after watching Crime Patrol, a popular Hindi crime anthology series created by Subramanian S. lyer for Sony TV. The kidnapped schoolboy was rescued by the police and reunited with his parents. Son of a gift shop owner from Basavanagudi area in Bengaluru, Chirag has reportedly told police that decided to make some quick money to spend on cricket betting and gambling after learning kidnap tricks from the ‘Crime Patrol’. According to police, Chirag reached a private school around 3pm on Tuesday on a Bounce rental bike and zeroed in on a fourth standard student who was walking out of school. He told the boy he was his father's friend and that he required help to search for a relative who had gone missing. The boy believed Chirag and rode pillion on the bike. Chirag then engaged the boy in conversation and learnt about his father's business and got his mobile phone number. He then made a call to the boy's father, demanded Rs 5 lakh and warned him against approaching cops. However, the boy's father alerted Cottonpet police and special teams were formed to crack the case. While Cottonpet inspector Venkatesh TC's squad verified CCTV footage in and around the school, Chamarajpet inspector BG Kumaraswamy's team started tracking the suspect's mobile phone movements. An hour later, the suspect's location was traced to a hotel on the Lavelle Road-St Mark's Road stretch. Police rushed there, rescued the boy and arrested Chirag.
