THIRUVANANTHAPURAM: Police will step up security for Chief Minister Pinarayi Vijayan following widespread protests in the state over the entry of two women at the Sabarimala shrine, a police officer said on Friday.

T K Vinod Kumar, chief of the police intelligence wing, said though the chief minister will continue to be in 'Z Plus' security category, some added precautions had been taken.

Accordingly, wherever the chief minister is or when he is travelling, roads will be sanitised, cleared of obstruction and police personnel will be more alert, said Vinod Kumar.

The pilot vehicle of the chief minister had on Thursday hit two Congress workers waving black flags when he was returning from office to his official residence for lunch.

Pinarayi, who is mostly based in the capital city oversaw the arrests of 109 Sangh Parivar activists on charges of unleashing violence in various parts of the capital city district.
