A Riyadh-Mumbai flight of IndiGo was diverted to Muscat following a "security alert" on Wednesday morning and it landed safely, the airline said here.
The aircraft is currently grounded in Muscat, IndiGo said in a statement. Notably, several flights have received threats that turned out to be hoax in the last few days.
"Flight 6E 74, operating from Riyadh to Mumbai, was redirected to Muscat due to a security-related alert. The aircraft has been isolated, and all passengers have been safely disembarked," the airline statement said.
It did not reveal the number of passengers and crew on board or other details.
"Ensuring the safety and security of our customers and crew remains paramount in all facets of our operations. We are working closely with the relevant authorities, and standard operating procedures are being followed," IndiGo said.
