New Delhi: In the second time in 24 hours, the official website of Delhi's Jamia Millia Islamia University was hacked.

In the early hours of Tuesday morning, the website (http://jmi.ac.in) displayed a birthday greeting, which read, "Happy Birthday Pooja. Your love," but was restored later the same morning.

However, another message flashed on the website post 9 pm on Tuesday, which read "Sorry, I Have a Boyfriend. ~ Pooja," suggesting that the website was hacked once again.

So far, no individual or group has claimed responsibility for either of the incidents but the website is now restored.

However, the hacking of a website twice in less than 24 hours has raised a serious concern regarding the security system of the country.
