A circuit court judge has discharged the jury in the trial of a 48-year-old man, charged with threatening to kill or cause harm to the founder of a Galway-based medical devices company.

David Corbett, with an address at St Clerans, Craughwell, Co Galway, has denied the charges.

He is accused of making statements to three men, which led them to believe he would kill or cause serious harm to his neighbour Ian Quinn.

The 65-year-old founded the Creganna medical devices company.

The trial began last week.

At Castlebar Circuit Criminal Court today, Judge Martina Baxter told the eleven member jury that matters had evolved and that the trial was being adjourned as a result.

She told the jurors that proceedings would take much longer than an initial estimate of three weeks.

Judge Baxter said that, in light of this, she was not going to delay jurors any longer.

As a gesture of appreciation, she said she was excusing the panel from jury duty for the next six years.

Mr Corbett has been charged under Section 5 of the Non-Fatal Offences Against the Person Act.

He is accused of making threats on dates between the 1 January 2012 and 28 February 2014.

Mr Corbett is also accused of harassing Mr Quinn on dates between 10 March 2012 and 31 July 2015 at various locations in Galway.

He has pleaded not guilty to all charges.
