Hyderabad: Upgradation of security cover for Andhra Pradesh Chief Minister N Chandrababu Naidu, who survived an assassination attempt by naxalites, acquisition of more bullet-proof vehicles and landmine detection equipment were among measures being contemplated to tone up the security system.

State Director General of Police S R Sukumara on October 14 said in the backdrop of gaping holes in the security drill that stood exposed in the aftermath of landmine blasts at Tirupati targetting Naidu's car, plans were on to acquire more sophisticated equipment since the present one was unable to detect the "deeply-embedded" landmines.

Though bomb disposal squads had sanitised the route taken by Naidu on October 1, when extremists triggered powerful landmine explosions on the ghat road at Tirumala foothills, the equipment that was used could not indicate presence of landmines, he told reporters.

"A genuine problem with the present equipment is that they cannot detect deeply-embedded landmines. We want to go for better equipment," Sukumara said.

Asked about the proposal for NSG (National Security Guards) cover for Naidu, who is top on the hit-list of the outlawed People's War Group (PWG), the DGP said, "It is a matter for the government to decide. As of now, the present security arrangement will continue."
