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.
