Passengers on a Kathmandu-bound aircraft of India's Jet Airways were evacuated minutes before take-off from New Delhi Wednesday due to a security alert, the second such incident this week on the same flight, The Daily Mail reported.

The plane's doors were closed and it was ready for take-off when the alert was raised, according to a Jet Airways spokesman. All 122 passengers and seven crew members were asked to leave the plane and security agencies were investigating.

The incident comes two days after the same Jet Airways' Delhi-Kathmandu 9W 260 flight was delayed due to a security scare, but investigations later found nothing unusual.

Police at Delhi's international airport were not immediately available for comment on what caused the security scare. Indian media said police received an anonymous call warning bombs were on two aircraft.

The other aircraft, operated by Air India, was also headed to Nepal's capital Kathmandu. The plane was taken to a bay area and security personnel screened the baggage, the company said on its Twitter account.
