'Both post-mortem reports (one conducted here and second in British) are same and both pointed out that the victim had suffered extensive injuries on the head and died of asphyxia,' Sharma said.

He said the police still suspected the involvement of Bhardwaj in the crime and had two theories - either Bhardwaj was jealous of his wife's friendship with Blakey or Blakey might have uncovered some financial scam in the charity, perhaps involving Bhardwaj.

However, he said it was not possible for them to interrogate Bhardwaj.

'We do not have enough evidence against him so far to initiate his deportation proceedings. It is now on the part of the British police to summon him again and try to find out his involvement, if any, in the crime,' he said, adding that they even did not know Bhardwaj's address and phone numbers in Scotland.

According to the police, Blakey visited this hill town in 2004. At that time he met Owen, who was planning to run a charity here with a Buddhist monk Jamyan. Blakey showed interest in the charity and helped her form the Tong-Len charity.

Between 2004 and 2006, both visited Britain many times to generate funds for the charity.

Bhardwaj met Owen in a small tea shop belonging to his uncle in October 2005 and they fell in love. They married in a traditional Hindu ceremony July 2006.

On Nov 26, 2006, Blakey suddenly went missing from the monastery where he was staying. His body was found in the graveyard two days after his disappearance. It was sent to his family in Britain after post mortem.
