With many flood-affected persons shifting to relief camps, police kept a watch on the locked homes to prevent possible cases of thefts and house-breaks, a city police release said.
On the directions of City Police Commissioner T K Rajendran, night patrolling was intensified, with over 350 jeeps and over 400 beat cops deployed for the job, it said.
"As a result, in some places, accused persons were held for trying to involve in theft (in such houses)," it said.
Medical camps were held for families of police personnel and they were being administered with preventive medication to safegaurd them from the any possible spread of epidemic, it said.
