Hyderabad, Nov. 28: Andhra Pradesh police have tightened Chandrababu Naidu’s security after indications that there could be another Tirupati-type attack on him, reports our special correspondent.

An attempt was made on the chief minister’s life on October 1 by the People’s War Group.

The list of visitors is being subjected to prior clearance by the police. The inner-ring of the security cordon has also been beefed up at Naidu’s residence and the secretariat, as well as for district tours, in view of campaigning for the impending elections.

The police suspect Naidu may be attacked when he campaigns in the Naxalite-dominated Telengana and Rayalaseema districts.

“The revolutionary cadres are disappointed that chief minister Chandrababu (Naidu) did not die in Alipiri (near Tirupati). We will have to make another attempt soon,” says the circular — allegedly written by a PWG leader — found on the body of a Naxalite killed in an encounter.
