Bengaluru's twin tunnel project to use slurry boring machines for excavation: Report
Plans for Bengaluru's new twin tunnel road, which will link Hebbal's Esteem Mall Junction and Silk Board Junction, will rely on slurry tunnel boring machines (TBMs) to do the heavy digging.

Their decision comes after evaluating the city's subsurface, which blends both stones and softer soil, making slurry TBMs a better fit for the job.

The massive venture is structured under a Build, Own, Operate, and Transfer (BOOT) model, which means successful bidders will be responsible for acquiring and managing the machinery, whether they import or locally assemble the TBMs themselves, the report stated. Past tunnel work in Bengaluru — like the Namma Metro — has achieved boring rates between 1.6 and 2 kilometres per year using similar technologies. The exact pace on this project will ultimately depend on the ground composition encountered during the drilling process. As part of the tendering process, the government is providing borewell survey information, but insists that detailed site investigation and analysis will be the winning bidder's responsibility.

Geological experts say the use of slurry TBMs may also help fill and secure natural fractures in Bengaluru's ancient, complex underground rock, some parts of which date back several billion years.

Bengaluru man arrested in Glasgow for provocative outburst on EasyJet flight, creating panic: Report
A 41-year-old man originally from Bengaluru was apprehended in Glasgow after creating panic onboard an easyJet flight by loudly expressing hostility toward US President Donald Trump and chanting religious slogans, according to police officials. The man, identified as Abhay Devadas Nayak, reportedly suffers from a psychiatric condition. The Bengaluru man, suffering from schizophrenia, sparked fear among passengers. (Image for representation) (REUTERS) ALSO READ | Bengaluru resident questions city's liveability after 9 years: 'We're all just surviving' Authorities have contacted Nayak's family in southern Bengaluru, who explained that he has been diagnosed with schizophrenia. Nayak is from a business family with roots in the Honnavar area of Uttara Kannada, while his siblings are doctors working overseas, The Indian Express reported. His family stated that he has traveled extensively and that his passport was issued in Bengaluru. The incident occurred on an easyJet flight traveling from London Luton airport to Glasgow on July 27, when Nayak disrupted the flight by shouting provocative statements, including threats about bombs and exclamations such as 'Death to America, death to Trump,' and 'Allahu Akbar.' Videos circulated online captured Nayak standing up, shouting, and then being restrained by fellow passengers and crew. During the scuffle, Nayak claimed that he was protesting because Trump was in Scotland that day, hoping his actions would send a message.

An ATM card in his wallet revealing his first name helped confirm his identity, the report said. ALSO READ | Japanese man compares Bengaluru airport to a luxury hotel: 'Never seen anything like this before' Scotland police reported responding to the disturbance after the plane landed in Glasgow at around 8:20 am on July 27. Nayak was taken into custody upon landing and appeared in court the following day without entering a plea. Official sources in Karnataka suggest that Nayak could be returned to India without formal charges being pressed. Public records from India show Nayak established a business, Antrix Ventures, in Bengaluru in 2010 with a relative. UK authorities have charged him with violations of the Air Navigation Order for recklessly endangering the aircraft and those onboard.
