LONDON – Detectives investigating the death of ex-Russian security agent Alexander Litvinenko sent a file of information from their probe to prosecutors Wednesday, a British police spokeswoman said.
London's Metropolitan Police said it could not say whether the file sent to Britain's Crown Prosecution Service made recommendations that individuals should be charged with criminal offenses over the death.
"We are not prepared to discuss the contents of the file," the police force said in a statement.
Litvinenko, a Kremlin critic who lived in exile in London, died in a London hospital on Nov. 23 after receiving a lethal dose of polonium-210. In a deathbed statement, he accused Russian President Vladimir Putin of ordering his killing, an allegation the Kremlin has denied.
London police have investigated the death in Britain and Russia. A team of British detectives traveled to Moscow to conduct inquiries last month.
A police spokeswoman said the investigation was not necessarily complete and that officers may seek to collect more evidence.
The Crown Prosecution Service confirmed officials had received the file and would now rule on whether anyone should face charges.
"The decision on whether there is sufficient evidence rests with the prosecution service," one of its spokeswomen said on customary condition of anonymity. "We have received a full file from the police, which contains all details of their inquiries into the case so far."
