Jaipur, Dec 26 (IANS): Some Rajasthan ministers, including the state home minister, have received threat e-mails allegedly from Indian Mujahideen (IM), warning them about bomb blasts in the state, police said Friday.

"The e-mails have been received by some cabinet and state ministers, threatening them that there will be bomb blasts in Rajasthan Jan 26," Rajasthan Director General of Police Omendra Bhardwaj, told IANS.

These e-mails were received Dec 22 at around 5.45 p.m.

"We got information about it Thursday. We are trying to investigate and verify the credibility of the mails," a police officer said.

"We have tightened security at major spots across the state as we do not want to take any chance," he said.

According to police, the e-mails are being sent by IM and they said that the ministers should be careful as the group is going to give them a "big bang surprise".

The mails said the ministers can now understand the goal of the group and do whatever they can. This should be taken as a warning and IM will conduct the blasts in various parts of Rajasthan Jan 26.
