An Indian official is calling for an enquiry into how government websites in the north-eastern state of Nagaland came to have links to pornographic websites.
The official, Kegunzulo Medhikhru, said he suspected some civil servants could have been involved, as the sites were too well protected from outside interference.
The BBC's Subir Bhaumik says the authorities in Nagaland, more used to scandals related to financial embezzlement and nepotism, have been caught off guard by the pornographic links.
The interference has affected the official website of the Nagaland Government.
But the website of India's National Informatics Centre (NIC) has also been attacked.
The NIC is a federal government body that links up India's state governments with federal ministries through the internet.
'Well protected'
The NIC's official in Nagaland, Kegunzulo Medhikhru, said the links to pornographic websites have now been removed.
He told the BBC the websites were well protected by firewalls, so it would not be easy for outside computer hackers to break into the site.
Firewalls are software that prevents a computer, or computer network, from being accessed by outside computers.
Mr Medhikhru said civil servants in Nagaland who had access to the government sites could be responsible.
