Since early morning this Sunday more contingents of police have been taking position at various zones on the Marina beach.
Most groups reported at the Gandhi statue spot and were then directed to various spots.
This security update seems to be related to an alert that there could be a surprise protest by the pro-Cauvery waters groups at the Marina.
A petition seeking permit to fast on the Marina has been going through twists and turns at the Madras High Court, with a Bench staying a single judge order allowing a farmer leader to hold a one-day fast on the beach.
Already, almost all paths to the beach are barricaded though beach-goers can access the sands and shore.
