New Delhi: The authorities on Thursday received a bomb threat for Air India's Toronto-Delhi flight, AI188, which landed safely in the national capital, sources said.

In the morning, the Delhi Police received a message claiming a threat to the flight. Following this, the Bomb Threat Assessment Committee (BTAC) was set up at Delhi airport and determined that the threat was “non-specific,” sources told PTI.

An Air India spokesperson confirmed that a security alert was communicated during the flight’s journey from Toronto to Delhi.

"On board crew carried out all the laid down security drills, keeping passenger safety & security as top priority. The flight has landed safely at Delhi and has been parked for the mandatory security checks by the security as per the protocol," the spokesperson said.

The airline official also stated that all passengers and crew had disembarked safely.

The flight, operated with a Boeing 777, landed at Delhi airport around 3.40 pm. According to flight tracking website Flightradar24.com, the Toronto-Delhi journey lasted just over 15 hours.

In the wake of the Red Fort blast earlier this week, enhanced security measures are in place at all airports, including compulsory secondary ladder point checks for all flights.

On November 10, at least 13 people were killed and several others inwere jured after a high-intensity blast ripped through a slow-moving car near Gate Number 1 of the Red Fort Metro station in Delhi.
