The Union Minister of State for Home Affairs said the Centre cannot intervene on its own but is willing to send extra forces to Tamil Nadu if the state asks for it.
"They haven't asked anything formally," Rijiju said, adding that the state has a significant number of central forces.
"If there is a law and order situation then the Centre is always willing to send extra forces. It is our primary duty to ensure that the state is being helped in whatever possible way they require.
He, however, said the Centre "cannot intervene on our its own".
Rijiju said the state has a significant number of central forces and whenever a need arises, it is calibrated and forces are sent.
Information and Broadcasting Minister Venkaiah Naidu said he spoke to Tamil Nadu Governor C Vidyasagar Rao and Chief Secretary and enquired about Jayalalithaa's health.
