According to unconfirmed reports, Justice Karnan is at present not in Tamil Nadu but at Srikalahasthi in neighbouring Andhra Pradesh. He is expected to return to Chennai this evening.
The judge was staying at a guest house after he arrived here yesterday before the apex court delivered its verdict. Later, he addressed the media in his room.
The Kolkata police personnel have spoken to their Tamil Nadu counterparts on executing the arrest order, the local police said.
This is the first time that a sitting high court judge has been awarded a jail sentence by the apex court on charges of contempt.
A seven-judge Constitution bench, headed by Chief Justice J S Khehar, had also disallowed the media -- print and electronic -- from publishing or airing the contents of further orders passed by Justice Karnan.
"The sentence shall be executed and he be taken into custody forthwith," the bench had said.
