A man who operates a trust building homes and schools in South Africa has been bound to the peace after he was convicted of public drunkenness and breach of the peace in Dublin last year.

Niall Mellon, with an address at Brentwood Court, Sandwich Road in Manchester, pleaded guilty to two charges today at Tallaght District Court.

A garda sergeant gave evidence that the 46-year-old was abusive to staff, members of the public and gardaí on 12 July last year.

At 12.30am on that date, gardaí went to a pub he owned at Taylors Three Rock after he called and told them a group there was dealing in drugs.

Evidence was given in Tallaght District Court today that Mellon began to square up to another man and gardaí ordered him out of the bar.

However, he refused to take a taxi home or leave the area.

Mellon was arrested after he abused gardaí and threatened to embarrass them in court. He continued to be abusive in Rathfarnham Garda Station.

Mellon said that, on the night in question, he had a meal with a friend in Dundrum, then had gone for a few drinks and there had been "a very hostile atmosphere" in Taylors Three Rock.

He said he still owned the pub, which is now under the control of NAMA.

Mellon also said that on 2 December last he had been talking on RTÉ Radio about the "death of a friend", Nelson Mandela, and was subsequently charged.

He pleaded guilty today to charges of public drunkenness and breach of the peace. He has one previous conviction for breach of the peace in 2005.

Judge Anthony Halpin told him his behaviour on the night had been "inexcusable" and bound him to the peace for 12 months.

Mellon, a property developer and philanthropist, is best known for operating a trust which has built thousands of homes and schools in South Africa's townships in recent years.
