The CBI’s overall conviction rate of 65-70 per cent, according to official data, is comparable to the best investigating agencies in the world. But this sterling performance doesn't cover the Central Bureau of Investigation's handling of abetment-to-suicide cases - of which not even a single has got to its logical conclusion. Nevertheless, the CBI, after the Supreme Court upheld the Bihar government's move, is now gearing up to probe actor Sushant Rajput's controversial death for which actress Rhea Chakraborty has been named prime accused of abetting his suicide. The agency has so far investigated a handful of such cases. In none of them, the CBI could prove that the suspect(s) drove the deceased to suicide. Will the CBI be able to find what out what happened to Sushant Singh Rajput? Watch the video to know more.
