According to PTI news agency reports, at six three schools received bomb threat mail. Bomb disposal squads and SWAT teams of Ahmedabad Police were dispatched for precautionary checks.
"Some schools in Ahmedabad have received emails threatening bomb blasts. So far, six schools have received such emails and have informed us about it. This seems to be on the lines of bomb threats received by schools in Delhi some days back," DCP cyber crime branch Lavina Sinha told PTI.
"As per our primary investigation, the email's domain is out of India," she said.
The local police, bomb disposal squad and crime branch personnel were checking the schools, the official said.
