Authorities at the Delhi airport on Friday searched a Vistara aircraft, which was to leave for Pune, following a bomb threat but nothing suspicious was found, police said.
In a statement, Vistara said flight UK971 had been delayed due to “mandatory security checks”.
A senior Delhi Police officer said a threat call received at the Delhi International Airport Limited (DIAL) control room in Gurugram was transferred to them through the Central Industrial Security Force (CISF).
Following the call, search and combing operations were launched.
