Bollywood superstar Amitabh Bachchan has alleged that his Twitter account has been hacked.

"WHOA !..My Twitter handle hacked ! Sex sites planted as 'following! Whoever did this, try someone else, buddy, I don't need this !", Bachchan tweeted.

Further information on the alleged hack was not immediately available.

Bachchan has 16.6 million followers on Twitter, even more than Prime Minister Narendra Modi.

An independent list has ranked Bachchan as the most influential Indian on the social media network, ahead of Modi, cricket star Sachin Tendulkar and the Dalai Lama.

The "hack" has not however, had an impact on anything on the actor's timeline, and attention was only drawn to the incident by Bachchan himself.

The offending porn sites have since been removed from the list of accounts he is following.

The actor's timeline was immediately filled with comments from concerned fans, including people who offered to track down the Internet Protocol (IP) addresses of the hackers.

In 2012, popular Indian director Karan Johar claimed that his account had been hacked by people who were sending direct messages to random people.

Kamaal R Khan, another actor and director also said that a stream of abusive messages on his timeline had been put there by "hackers".

Twitter India declined to make a statement on Bachchan's tweet, saying that they did not comment on individual accounts.
