Tycoon Badri Patarkatsishvili died of natural causes, according to the initial post-mortem examination. Toxicology testing, however, is still required, the local police in Surrey, Britain where Patarkatsishvili died late on February 12, said.

"Surrey police can confirm that at this stage there is no indication that the sudden death of Badri Patarkatsishvili was from anything other than natural causes. However, extensive toxicology testing is yet to be carried out. This will take a number of weeks," Reuters reported quoting a police spokeswoman.
