Bengaluru: With surveillance levels high across the city in the backdrop of Indo-Pak tensions, a chilling call to police shattered the stillness of the early-morning hours Monday.The message was alarming: “A man with a gun has entered the pub.”The message triggered a chain reaction with scenes unfolding like in a gripping thriller: The area was cordoned off. Armed commandos descended with their assault rifles. Drones were brought in to scan rooftops. And, bomb detection and disposal squad personnel were kept on standby. The drama unfolded atGeometry Brewery and Kitchenin Rajajinagar II Stage after one of the security guards, Vikas, noticed suspicious movements inside the pub around 3.35am. He noticed an intruder had broken the lock of a door and entered the building. Vikas called his supervisor, Vinay Kumar, at 3.38am and the latter, along with office attendant Shyam, rushed to the spot. In his complaint, Vinay told police he asked Vikas to stay outside the door at the entrance while he and Shyam went into the building.Vinay noticed that the main switch of the building had been turned off by the miscreant.Power supply to the lights and CCTV had also been disconnected. They both used the torch on their mobile phones and went in search of the intruder. They spotted a person near the office of the pub owner on the third floor. As they neared him, the intruder threatened to attack them with a weapon, which appeared to be a gun. The miscreant then asked Vinay to reveal where the money was. Fearing the gun, Vinay showed him the drawer in his boss’s chamber. The miscreant broke the drawer and took Rs 50,000, Vinay told police.With the same weapon, the miscreant threatened Vinay and Shyam not to raise an alarm and entered another room on the same floor. Vinay and Shyam rushed out of the building, and assuming that the miscreant was still in the building, they dialled 112 and complained. A police team visited the spot by 4am. They told cops that the miscreant was aged 24-26 years and had covered his face with a mask.The two words, gun and pub, were enough for police to quickly swing into action. A few cops on night patrol from Subramanyanagar police station and neighbouring police stations reached Geometry and surrounded the building. Later, a quick reaction team (QRT) consisting of around 15 personnel with rifles surrounded the building. But after nearly six hours of intense search and suspense, the episode ended not with a standoff or a shootout, but a surprising twist: The armed intruder could not be found!A senior officer said: “We verified CCTV footage from the surrounding buildings and found that the miscreant jumped from the first floor of the building through a sliding window.” A case has been registered under BNS for robbery and house-trespass or housebreaking. “We are investigating from all angles. But, we are sure it has nothing to do with the conflict situation; it is an incident of theft which became robbery as he threatened the pub staff,” an officer said. DCP (north) Saidulu Adavath camped on the premises and supervised the operation. Around 9am, he announced that the miscreant had managed to escape.
