A Ranchi bound plane was delayed at the Indira Gandhi International (IGI) Airport here on Wednesday after the authorities got an anonymous call about weapons in the aircraft.
The airport authorities deplaned all the passengers from the Go Airways aircraft and conducted a thorough search before granting it a security clearance for take-off.
The origin of the anonymous call is yet to be ascertained.
Last Wednesday, multiple bomb scares in Kathmandu bound flights from Delhi had halted the operations of Jet Airways and Air India flights.
Both flights were checked by bomb disposal squads in Delhi.
