Day after a bomb blast near CRPF Public School in Rohini's Prashant Vihar, two Central Reserve Police Force (CRPF) schools in Delhi and one in Hyderabad, along with two Kendriya Vidyalayas on the forces' office premises in other cities received bomb threat via email late Monday night, officials said on Tuesday. The threat turned out to be a hoax, reports confirmed.
Anti-sabotage teams inspected the schools but nothing suspicious was found, said sources, adding that classes were conducted smoothly on Tuesday.
The three CRPF schools include two in Delhi (Rohini and Dwarka), one in Hyderabad (Telangana); while the two Kendriya Vidyalayas are within the paramilitary forces' office premises at Panchkula (Haryana) and Rampur (Uttar Pradesh).
Requesting anonymity, a senior Delhi Police officer said the cyber cell has launched a probe in to the threat mail.
He also said Delhi Police has written to the email service provider to get the user ID and other details of the sender.
Sources said in the e-mail, the sender has also mentioned about politics in Tamil Nadu and sacked DMK functionary Jaffer Sadiq.
The officer said a Delhi Police cyber cell team has been constituted to probe if the threat was in any way linked to a blast Sunday morning at the CRPF Public School in Rohini's Prashant Vihar in Delhi. Security and intelligence agencies are probing the role of Khalistani supporters in the Sunday morning blast.
The latest threat email was received by Monday night. It claimed that the improvised devices may explode on the schools' premises by 11 am Tuesday.
The CRPF schools are run by the country's largest paramilitary force that is deployed in three major combat theatres of anti-Naxal operations, counterterrorism in Jammu and Kashmir and counter-insurgency in the Northeast.
