How can you detect an attacker, having Yandex logs and bitcoin exchange logs on hand?

Question

Burglary protection

When I logged into my btc-e account today, I did not find any funds on the account. In the transaction history, I saw that everything was transferred to an unfamiliar wallet. Funds worth about 2 bitcoins. The btc-e account was registered to Yandex mail with the same password. Yes, weed.
When transferring funds, the exchange sends a confirmation letter. The Yandex logs show that the attacker went to the mail several times, read, deleted letters. At the same time, it has dynamic IP addresses and one provider.

Mail entrance 91.214.131.65 Ukraine A
letter

letter

Mail entrance 87.244.179.99 Ukraine

From the IP addresses of this provider, the btc-e account was also logged in.
Now the question is: how can an attacker be detected, having Yandex logs and stock exchange logs on hand? Is it within the competence of the Russian police to bring to justice a person from a brotherly state and, ideally, return the funds to the account? And what actions should be taken for this?

Answer 1

Forget it.

Answer 2

Unauthorized access to someone else's mailbox, no? For this, there were quite courts. Well, how to attract bitcoins here in terms of their current rate is a separate question.

Answer 3

Whatever the outcome of the investigation, the main thing is to draw conclusions:
use password managers, for example, Keepass

Answer 4

It's not even WebMoney, he stole bitcoins. Even if you really want to, you will not succeed.
Even if you miraculously find him, you are unlikely to be able to return the money and prove that he stole it.
