The police on Tuesday termed the death of Paranormal Society founder Gaurav Tiwari a suicide and ruled out any foul play.

"It is a clear case of suicide. Exact cause of death can be only ascertained after a detailed report of the post-mortem is received," Deputy Commissioner of Police (South West) Surender Kumar told IANS.

"As per the available details with me right now, there is no foul play in his death; till the time nothing new comes out of the autopsy report," Kumar said.

"Even his family members have not pointed towards anything suspicious," the officer said, adding, "So we don't find anything suspicious as there is no other bodily injury."

Tiwari had got married in February this year. His wife, father and mother, were present at home at the time of the incident, a police officer said.

Tiwari, CEO of Paranormal Society, was found dead under mysterious circumstances in the bathroom of his flat in Dwarka area of west Delhi on July 7.

According to police, the doctors in its preliminary autopsy report suggested asphyxiation as the cause of death. A thin black line across his neck was discovered by the doctors and police.

He usually used to stay out for "ghost hunting" quite late into the night. A day before his death Tiwari was investigating a suspected haunted house in Delhi's Janakpuri area and returned home at around 1.30 a.m. at night.

Paranormal Society was established in 2009 by Tiwari. According to its website, Tiwari was once a 'commercial pilot' and had visited over 6,000 haunted places across the world. He had also investigated UFO abductions and mysterious creatures.

The Paranormal Society founder had also worked on various TV shows including 'Fear Files', 'Haunted Weekends with Sunny Leone', 'Bhoot Aaya' and others.
