Bomb threats to flights of Indian airlines continued Wednesday with at least six flights — three of IndiGo, two of SpiceJet and one of Akasa Air — being the latest additions to the growing list. With these six flights, the number of confirmed instances of bomb threats to Indian carriers’ flights over the past three days has risen to 19.

Three international flights — one of Air India and two of IndiGo — had received bomb threats on Monday, while another ten flights spanning all major carriers had received threats on Tuesday. All the threats on Monday and Tuesday came via social media platforms, and eventually turned out to be fake.

Union Civil Aviation Minister Kinjarapu Ram Mohan Naidu Wednesday expressed deep concern over the “disruptive acts”. Stating that such “mischievous and unlawful” actions are a matter of grave concern, the minister condemned “attempts to compromise the safety, security and operational integrity of the aviation section

In his statement, Naidu also said that the Mumbai Police has apprehended a minor responsible for issuing bomb threats to three flights, and added that others responsible for the disruptions will be identified and prosecuted.
