Alleged robbers were disrupted as they tried to break open a cash box seized during a security heist in Co Antrim, the High Court heard yesterday.
Police swooped on a house in Dunmurry after hearing grinding noises coming from an upstairs room, prosecutors said.
Two suspects tried to escape, one by attempting to climb out of a window, a judge was told.
Details emerged as one of the men detained during the operation was granted permission to live on bail at a different address.
Richard Scullion (48), of Churchill Park, Portadown, faces charges of robbery and handling stolen goods. He was allowed to return to his home for three days over Christmas.
He is one of a number of men accused in connection with the seizure of a cash box containing £16,500 near Lisburn in July.
The court heard it was taken from a security guard who had a knife thrust towards his face.
