A 23-year-old man has been charged with the robbery of £26.5 million from the Northern Bank in Belfast last December.
A PSNI spokesman said the suspect has also been accused of falsely imprisoning a husband and wife and possession of a firearm or imitation firearm.
He is the first to be charged in connection with the heist, which happened just days before Christmas last year.
The man was one of five men arrested over the past two days by detectives investigating the robbery.
Three remain in custody while one man has been released without charge.
The PSNI's Chief Constable Sir Hugh Orde has said he believes the IRA carried out the raid, an allegation strenuously denied by Sinn Féin.
Last February as part of an investigation into IRA money laundering, gardaí in Cork and Dublin seized £3 million - £60,000 of which was linked to the Northern robbery.
The rest of the money has never been recovered.
