Text messaging has become a crime-fighting tool for India's Central Bureau of Investigation.

The CBI has launched a campaign through which it is urging India's populace to report, via text messages, government corruption, according to at least one report.

The idea, as one source described it, is about "putting the fear of getting caught" into those government officials involved in corruption.

While it can take years to get a conviction, says a former CBI official, the texting campaign is helping to build a database of officials who need to be watched.
