Six to seven schools in Ahmedabad on Monday received emails threatening to blow up these institutions, police said.
Schools like Delhi Public School (DPS) and Anand Niketan said they got bomb threat emails and contacted the police control room.
Police teams reached various schools in the city with bomb squads after receiving information about the threatening emails.
The development came nearly a week after more than 150 schools in Delhi-NCR and one in Lucknow received a bomb threat email, prompting mass evacuations. The police later said that the bomb scare turned out to be a hoax.
