The All India Football Federation`s (AIFF) website on Tuesday was hacked by an anonymous group called "Zero Cool".
The group posted anti-India messages on the website.
Most of the messages referenced Kulbhushan Jadhav.
One of the messages read: "Do you need Kulbhushan Jadhav back?"
Another read: "We will send you his Dead Body."
Pakistan has sentenced Jadhav to death -- it says he was a spy -- but the International Court of Justice stayed the sentence Tuesday.
The website was later restored, with the AIFF saying: "Our website has been restored, after what we call a 'reckless sliding tackle', caused us a slight problem."
UP AND RUNNING! Our website has been restored, after what we call a 'reckless sliding tackle', caused us a slight problem. #BackTheBlue— Indian Football Team (@IndianFootball) May 10, 2017
