"After the Sunday incident in Patna, officials in various districts have been asked to maintain vigil and step up intelligence," Inspector General of Police (Law and order) R.K. Vishwakarma said.
"Instructions have been issued to maintain fool proof security for all political rallies and now specially for the Gujarat chief minister," he said.
Vijay Bahadur Pathak, state spokesman of the BJP told IANS that so far the party was okay with the security set up at Jhansi and Kanpur.
Pathak, however, added that with new security concerns cropping up after the Patna blasts, the Uttar Pradesh government should ensure that security and checking of people coming for the rally is adequate and done properly.
Senior BJP leader Murli Manohar Joshi also Sunday demanded at Lucknow that the security of Narendra Modi be further beefed up in view of the Patna serial blasts.
A string of rallies have been planned by the SP, Congress and BJP in the coming months. While the SP will start its political campaign for the Lok Sabha polls 2014 from Tuesday at Azamgarh, Congress vice president Rahul Gandhi will address two rallies in Hamirpur and Salempur Oct 30.
