A 23-year-old man has tonight been charged with the robbery of £26.5 million from the Northern Bank in Belfast last December.
Dominic McEvoy, of Kilcoo, Co Down has also been accused of falsely imprisoning a husband and wife and possession of a firearm or imitation firearm, a PSNI spokesman said.
Mr McEoy is one of five people arrested in connection with the raid in the last 48 hours. All five are being held in Antrim police station.
Earlier today police arrested two men - one in Dungannon and one in Coalisland - in connection with the raid - the biggest in British or Irish history.
Three other men were arrested over the past two days as part of the ongoing investigation.
Earlier chief constable Sir Hugh Orde said the arrests were a significant part of the investigation and expressed his hope that more would follow.
"This is not over yet," he said. "Just because people have been arrested today does not mean the investigation is closing down."
The December 20th robbery at the Northern Bank's headquarters in central Belfast, in which the families of two bank workers were held hostage, severely dented efforts to revive government set up under the Belfast Agreement.
While nobody has been charged up until now in connection with the raid constable Orde has consistently indicated he believes the IRA was behind the raid - a claim which the paramilitary denies.
Police on both sides of the Border have so far only recovered relatively small amounts of cash believed to be linked to the raid.
About £60,000 in used Northern Bank notes recovered in Co Cork last February as part of an investigation into a suspected IRA money-laundering has been linked to December's raid in Belfast.
In a bid to thwart attempts to launder the cash, the Northern Bank withdrew all its paper currency, but police said up to £10 million of the haul was untraceable.
Last March the bank was forced to replace all its £10, £20, £50 and £100 notes with new notes carrying a different logo.
