Two private schools in Agra received bomb threats through email on Wednesday, prompting extensive searches by bomb disposal and dog squads, but nothing has been found yet, Police said.
Assistant Commissioner of Police (ACP) Vinayak Bhosale said Shri Ram School and Global School received threatening emails.
"Both schools were thoroughly checked by the bomb disposal squad and dog squad. No suspicious items were found in either school, he said.
Normal academic activities have resumed, with students continuing their studies as usual, the officer said, adding the cyber cell has initiated an investigation into the origin of the emails.
