Russian prosecutors say they have identified suspects in the murder of the first deputy chairman of Russia's central bank, Andrei Kozlov.
Mr Kozlov was in charge of licensing commercial banks
"The people linked to organising and carrying out this crime have been identified," the prosecutor general's office said.
Mr Kozlov, 41, was shot dead at a Moscow sports ground on 13 September.
Under his supervision, the central bank had shut down dozens of banks in a crackdown on money-laundering.
Russian media reported that three Ukrainians had been arrested in connection with the murder. That was not confirmed by the prosecutor-general's office.
