The Police swung into action after nearly a dozen Indian flights, including some international flights, received bomb threats in the last two days. However, nothing suspicious was found in the planes and these threats turned out to be hoaxes.

The Delhi Police has registered an FIR in connection with bomb threats to several domestic and international flights in the last two days and launched a probe into the matter, official sources said on Wednesday.

The Delhi Police have registered at least six First Information Reports (FIRs) related in connection with bomb threats received by multiple airline companies in the last couple of days.
