The veteran movie star told his fans on the social networking site that cyber-crooks had targeted his account and signed him up to follow tweets from several sex websites.

Hours later he revealed the hack attack had led him to make a connection with abusive SMS messages he has been receiving on his cell phone, and he has now asked police to investigate.

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

He later added, "OKAAY... !! Plot thickens! Had been getting several really dirty abusive sms for a year... just handed all of them to the POLICE!"
