The Supreme Court on Friday extended by a week the parole granted to AG Perarivalan, convict in the Rajiv Gandhi assassination case, and made it clear that no further extension will be given.

A three- judge bench headed by Justice LN Rao granted the parole to the convict on November 23 for a medical check-up.

Perarivalan is serving a life-term at Puzhal Central Prison near Chennai in Tamil Nadu.
