Six flights against which bomb threats were made via social media made scheduled landing at Mumbai's Chhatrapati Shivaji Maharaj International Airport on Saturday, a police official said.

These threats came from a single X account and were categorised as "hoax" and "non specific" after thorough checks, the official added.

The account, of a user named 'Adha', mentioned flights of several airlines, though only six were scheduled to land at Mumbai international airport, the official said.

These were from Delhi, Goa, Darbhanga etc, the police official informed.

As per sources, more than 30 flights operated by various Indian airlines received bomb threats since Saturday morning.

They said flights of Air India, IndiGo, Akasa Air, Vistara, SpiceJet, Star Air and Alliance Air have received threats. In at least one of the flights, a note was found in the lavatory saying there was a bomb on board.

The Civil Aviation Ministry plans to put in place strict norms to prevent incidents of hoax bomb threats to airlines, including placing the perpetrators in the no-fly list.

Mumbai police, which has filed multiple FIRs over such threats, had detained a minor boy from Chhattisgarh with regards to one of them.
