The Central Bureau of Investigation (CBI) has ruled out any foul play in the "mysterious death" of Akshay Singh, a Delhi based journalist who had died while trailing the infamous Vyapam Scam in Madhya Pradesh's Jhabua district.

The probe agency had registered a preliminary enquiry (PE) into the death of the 38-year-old journalist that took place on July 4, 2015 and sources now say that investigators have completed its probe.

"Our investigators have completed their probe and have ruled out any chances of a foul play," a senior CBI official said indicating the death was natural.
