It's been almost two years since his son, reality show "Voice of India" winner Ishmeet Singh, died in suspicious circumstances in the Maldives, but Gurpinder Singh is still seeking justice from the authorities.

"Nothing has changed. I want the media to ask the CBI about what happened to Ishmeet's case. What actions are being taken to find the truth about his death? What did the CBI do? Why are they quiet? Why is no one asking them now?" said Gurpinder Singh.

He recently underwent past-life regression therapy on NDTV Imagine's show "Raaz...Pichhale Janam Ka" to find a connect with Ishmeet's death from his own past life.

Ishmeet died at the age of 19 under mysterious circumstances in the Maldives. He had gone there for a performance, but drowned in a swimming pool at the Chaaya Island Dhonveli beach resort July 29, 2008.

Though his father approached Prime Minister Manmohan Singh to request a Criminal Bureau of Investigation (CBI) probe into the death, he hasn't got a concrete response yet.

Recently, when Gurpinder Singh underwent regression therapy on "Raaz...Picchale Janam Ka", he found that he had a son named Ishmeet in his last birth too - and even he used to sing.

Singh traced himself back to London somewhere during the 1930s. His name was Raunak Singh and he was a singer by profession.

"I saw Ishmeet in my last birth. We were from a well-to-do family. But due to one incident, he died at the age of 16. There was a point during the regression when I felt that I was being told that - 'You will have a son in the next life but he will live only till he's 19', and that's just what happened, " said Singh.

"As a common man, I think that the pressure on the CBI is no longer there. They have just written it off as just any drowning case and are not following it up. They told me that whenever they will reach some conclusion about it, they will go to the media... But I want to ask them that it's been almost two years, what have you done?" he said.

The episode featuring Ishmeet's father will be on air Wednesday at 9.30 p.m.
