Ahmedabad: On the eve of Lok Sabha elections in Ahmedabad, as many as 10 schools here received an email on Monday threatening bomb blasts, though a police statement said this was a hoax as searches failed to unearth anything suspicious. After being alerted, police as well as bomb detection and disposal squad, dog squad and Crime Branch teams reached these schools and conducted a thorough search, a statement by Ahmedabad City Crime Branch informed. “No explosives were found during the search operation. Our teams are patrolling these areas and technical surveillance has also been initiated about the sender of the email. We appeal to people not to panic and to stay away from rumours. This threat was a hoax,” the statement said. The schools that received the threat email included DPS and Anand Niketan in Bopal, Udgam School on SG Highway, Calorx School in Ghatlodia and Kendriya Vidyalaya at Chandkheda. “A preliminary probe has revealed it was a hoax and the threat was given to disturb the peaceful atmosphere in view of voting on May 7,” district education officer Rohit Chaudhary said.
