Panic gripped an Air Canada Toronto-bound flight after the Indira Gandhi International (IGI) Airport here received an email claiming a bomb had been planted on the airplane, officials said on Wednesday. The threat turned out to be a hoax.

The Delhi International Airport Limited (DIAL) office received an email at 10.50 pm on Tuesday stating that a bomb had been planted in the Delhi-Toronto Air Canada flight, the officials said.

“Following standard security protocols, a thorough inspection was conducted and nothing suspicious was found,” a senior police officer said.

Legal action in the matter is being taken, he said.
