A US lawyer has been jailed for four months following an air rage incident on a transatlantic flight.

Timothy Fassano, 49, was arrested at Dublin Airport on 23 April after a passenger plane bound for JFK Airport in New York was forced to divert to Dublin.

Fassano was charged with engaging in behaviour that was of a threatening, abusive and insulting nature with intent to provoke a breach of the peace on Flight LH410.

He was also charged with behaviour likely to cause serious offence or annoyance despite being requested by aircraft crew to stop.

It was also alleged he was intoxicated to such an extent to give rise to an apprehension he might endanger himself or others.

At his first hearing on 24 April his solicitor Tracey Horan told Dublin District Court that her client was an attorney-at-law, but he is currently of limited means and does "locum" work.

Fassano, with an an address at 90th Street, Queens, New York, was granted bail with conditions that he had to sign on daily at Store Street Garda station in Dublin, surrender his passport and tell gardaí where he would be staying.

His next scheduled hearing was on 29 April but he did not show up and the court heard that he had been spotted in Dublin’s city centre looking "less for wear".

A bench warrant was issued to have him arrested.

Separately, he was picked up by gardaí later that day at Church Street, and charged with being drunk in public.

He was brought before a late sitting of Dublin District Court last Tuesday and was remanded in custody.

Today, he pleaded guilty at Cloverhill District Court to all the charges against him.

Judge Victor Blake sentenced him to four months in prison and fined him €750.
