The CEO and founder of Indian Paranormal Society, Gaurav Tiwari, was found dead under mysterious circumstances in his residence in Dwarka on Thursday.
According to Times Of India, police said the 32-year-old committed suicide. However, they have not been able to ascertain the motive behind the suicide.
Gaurav's family believes that he was "perfectly normal" and they don't believe that he killed himself.
Gaurav, a pilot by training, had visited over 6,000 'haunted' locations and investigated hauntings, 'UFO abductions' and 'mysterious creatures', notes the Indian Paranormal Society website.
Gaurav's father, Uday Tiwari, told ToI that he had got married just a few months ago.
"He told his wife a month ago that a negative force was pulling him towards it. He had said he was trying to control it but seemed unable to do so. My daughter-in-law ignored it thinking he was just depressed due to work overload and did not tell us about it," he said.
"We don't believe in ghosts etc, but his death has left us shocked and puzzled," Uday added.
Investigators said there was a black line around his neck when they found him and the cause of death seems to be asphyxiation. They are now waiting for a full autopsy report.
