MOSCOW, June 17 (RAPSI) - Russian bailiffs are still waiting for the British authorities to send them an official confirmation of businessman Boris Berezovsky's death, the Federal Bailiff Service told RIA Novosti on Monday.

The service earlier said that its Moscow department was considering five cases concerning Berezovsky for an outstanding debt of 3.3 billion rubles ($103.8 million).

Federal Bailiff Service head Artur Parfyonchikov said an official confirmation of Berezovsky's death was needed to take further decisions regarding the debt collection cases.

The chief bailiff said at the time that there were joint debtors in Berezovsky's cases and the cases remained open.  The bailiffs are also monitoring the late businessman's assets.  "At this stage, we have no documents confirming his death," the source said.

Berezovsky was found dead in his Berkshire house on March 23.

The first results of a post-mortem examination determined that the cause of death could have been hanging. The investigation is underway. The British media report that the former oligarch was on the verge of bankruptcy after losing several litigations against his former business partners.

In 2012, he lost a case in London against fellow Russian tycoon Roman Abramovich and agreed to pay litigation costs of 35 million pounds.
