Megastar Amitabh Bachchan is back on micro-blogging site Twitter after it was hacked and adult sites were planted on it.

The 72-year-old actor tweeted about his "scintillating experience" of attending a musical performance by the slum kids of Dharavi.

"Moments with the ‘Dharavi Rock Band’… Scintillating experience… RJ Malishka and organisers, well done!! Kids from band of Dharavi, arguably world’s largest slum, were all ‘rag pickers’… Music changed them all," he tweeted.

The ‘Piku’ star filed a complaint with the police against the "dirty, abusive" smses that he has been receiving for the past one year.

Bachchan, who boasts more than 16 million fans on Twitter, requested the police to investigate the matter and take action against the perpetrators.

Big B uses different platforms– Twitter, Facebook and his blog– to interact with his fans and update them with his projects and personal life.
