The trial of a man accused of kidnapping a family as part of a post office robbery has collapsed.

Jonathan Gill, 35, of Malahide Road, Swords, Dublin, is accused of kidnapping a Drogheda postal worker, his partner and their ten-week-old baby daughter before robbing €660,000 from the man's workplace.

The jury of seven men and five women had deliberated for a total of just over 14 hours since last Thursday following the month-long trial.

On day five of its deliberations Judge Elma Sheahan told the jury that due to information that has come to the court's attention she was discharging the jury from its duty.

She said it was regrettable but inevitable that the case must come to an end.

It is the State's case that Mr Gill was one of a group of five who were involved in holding the family hostage in their own home before moving them to a shed about a 90-minute drive away.

Mr Gill has pleaded not guilty at Dublin Circuit Criminal Court to falsely imprisoning Warren Nawn, Jean Marie Nawn and their baby girl in Drogheda between 1 and 2 August 2011.

She remanded the accused on continuing bail until 28 April.
