New Delhi:

Two hospitals in Delhi received bomb threats this afternoon, days after panic swept the National Capital Region after similar threats went to more than 100 schools. The threat e-mails were sent to Burari Hospital and Sanjay Gandhi Hospital. The Mangolpuri police said no device was found despite an extensive search by them, along with the bomb disposal squad, the fire service and other teams.

Last week, schools at Delhi and Gujarat’s Ahmedabad received bomb threats which turned out to be hoax.

The e-mails were sent to 131 schools in Delhi, five in Gurugram, and three in Noida and  Greater Noida on May 2.

Three days later, three schools in Ahmedabad also received threats.

The schools had received the emails from a single IP address, likely masked using a VPN connection, reports said. It is likely they originated from a Russian domain.

The perpetrators had used the Arabic word ‘Sawariim’, meaning clashing of swords and associated with ISIS propaganda. But investigators have said it is unlikely that the ISIS is involved.
