According to media reports, the email received on Thursday, Aug 13 threatens of violence if a separate muslim state comprising districts of north Kerala is not created.
The state's cyber cell police have traced the email and found that it was sent from the United Arab Emirates (UAE).
"We immediately began our work and found that the mail is from United Arab Emirates based Etisalat and the domain is that of Yahoo. Since a first information report is required to trace out the IP of the computer, a case has been registered here at the Kannur Town police station," inspector general of police Tomin J. Thachenkery was quoted as saying in a new agency report.
"If their demand for a separate Muslim state is not met, then bombs will be deployed across the state and for that they have already shipped seven kilograms of RDX. The first of the series of bomb blasts will begin with a sample one today (Friday, Aug 14), being the Independence Day of Pakistan," the letter said added Thachenkery.
He also revealed that the e-mail was written by Zakhir Hussain who claims to be the head of the newly formed Malabar Mujahid which has its headquarters in Karachi and has support from ISI (Inter-services intelligence) of Pakistan and LeT (Lashkar-e-Toiba).
