The niece of fashion designer Ralph Lauren has appeared in court accused of being drunk and disorderly on a New York-bound plane during an alleged air rage incident.

Jenny Lauren, 41, was arrested accused of breaching the peace after the Delta Air Lines flight from Barcelona was she on had to be diverted to Shannon Airport in Ireland following the alleged incident.

Lauren, a jewellery designer, did not enter a plea at Killaloe District Court. The hearing was forced to take place in the downstairs of a pub as the area does not have a courtroom.

The case will be dealt with at a second hearing at Ennis District Court on 8 January.

The US national was granted bail on the condition she stays at a hotel in Shannon and surrender her passport.

Police officer Yvette Walsh told the hearing that when Lauren was being arrested at the Shannon Airport she told officers: "Can you say that in English, please?"

Lauren is accused of being intoxicated to such an extent as would give rise to a reasonable apprehension that she might endanger herself or other persons on board the aircraft, as well as engaging in behaviour likely to cause serious offence or annoyance to any person on board the aircraft.

She also faces another count of breaching the peace by engaging in threatening, abusive or insulting behaviour.

Judge Patrick Durcan said Lauren had indicated she would plead guilty to the charges.
