British police investigating the poisoning death of a former KGB spy have officially requested assistance from their Russian counterparts and are soon due in Moscow to collect information, prosecutors said Monday.
Alexander Litvinenko, 43, died Nov. 23 in London after being exposed to a rare radioactive element.
The Prosecutor General's office said in a statement they have agreed to help Scotland Yard officers in their probe. A Foreign Ministry spokesman said Russia has already issued visas for the team, reports AP.
British law enforcement authorities have said a team of nine officers plan to travel to Moscow within days to interview several people, including Andrei Lugovoi, another former spy who met Litvinenko on Nov. 1 the day he fell ill. FBI agents have also been involved in the probe.
In a deathbed accusation Litvinenko blamed Russian President Vladimir Putin for the poisoning. The Kremlin has vehemently denied the accusations.
