The threats came in the form of text messages and voice mail messages that originated from Russia. Before Sergei died, we received messages. Text messages came to one of our Russian lawyers in London that said, “What's worse? Prison or death?” Shortly thereafter, we got a message saying, “History tells us that anyone can be killed”, quoting Don Michael Corleone of The Godfather.
I then received a voice mail message of someone being severely beaten, and then after Sergei died, we received several more of these messages, including one--I won't repeat the swear words that came in it--that said, “We're coming to get you”, and then it was swear, swear, swear.
Since we all live in London, all these messages were reported to the SO15, which is the anti-terrorist unit of the Metropolitan Police, and a case file has been opened and a number of things are being done. Again I don't want to go into too much detail in a public forum, but it's something that they take seriously and that we take seriously. We're just doing the best we can under the unpleasant circumstances of having a rogue regime not happy with what we're doing.
