In a second such incident since May 12, the Ahmedabad airport on Monday received a bomb threat via an email.

The threat mail prompted security personnel to launch a search operation.

However, after through search of the premises, officials did not find anything suspicious.

Officials said that the threat turned out to be a hoax, reported PTI.

SG Khambhala, inspector of airport police, said that nothing suspicious was found after the premises of the Sardar Vallabhbhai Patel International Airport was searched for more than two hours by local police and Central Industrial Security Force (CISF) personnel.

The search operation involving teams from local police, the CISF and a bomb disposal squad (BDS) went on for two-and-a-half hours, PTI quoted Khambhala as saying.

On May 12, a similar threat mail was received by Ahmedabad airport authorities. However, even then, nothing suspicious was found.

On June 18, the Vadodara airport in Gujarat received a threat email.

Over the last few months, several institutions, schools and airports in the country have received a bomb threat via an email which later turned out to be a hoax.
