"A huge burden on Delhi police at this sensitive time. All leaves are cancelled, definitely don't need abuse and diversions at this time," Minister of State for Home R P N Singh wrote in microblogging site Twitter.
The leave was cancelled to provide foolproof security in the run up to and during the coming Republic Day function, he said.
Singh said around 4,000 security personnel have been deployed in and around the site of dharnas of Kejriwal.
