The bomb threat was logged at 6:05 pm, prompting the Bomb Threat Assessment Committee to label it as specific and relocate aircraft 6E588 to a designated isolation bay. By 6:55 pm, all 150 passengers had been safely de‑boarded.
Security teams performed an exhaustive anti‑sabotage sweep, inspecting the cabin, cargo hold, and fuel lines, a process that usually takes about three hours but in this case stretched over four. The crew reported no suspicious devices and the aircraft remained sealed until clearance.
The threat assessment was dismissed at 9:20 pm after the checks, and the plane was handed back to IndiGo for operations. The airline rescheduled the flight for 10:30 pm, nearly five hours behind its original timetable.
Chennai Airport officials stated no foul play was found and urged calm, while passengers voiced frustration over the extended hold. IndiGo issued a public apology and offered vouchers to all affected travelers.
