Huh? This article is so poorly written, I’m not sure that happened. Either the reference sample of the murder victim was incorrect, or the cops sent the wrong body.

“The DNA report from Mohali-based forensic laboratory has confirmed that the body flown to London by police was not of UK-based NRI Ranjit Singh Powar who was allegedly murdered last year, it is learnt.”
