Sligo developer Cathal O’Connor has started a prison sentence for assault but remains a director or secretary of 21 separate companies linked to his property empire.O’Connor, of Beldare Homes, a big landowner, pleaded guilty in April to beating three 13-year-old boys in 2024 after finding them in a property he owned in a business park.Sligo Circuit Criminal Court imposed a five-year sentence on him in May with the final three years suspended for six years. The start of the sentence was deferred for two months until July 1st to allow him settle business affairs. He began the sentence on Wednesday in Castlerea Prison, Co Roscommon, but no information was provided on his committal. “The Irish Prison Service does not comment on individual prisoner cases,” the service said in reply to questions. The ruling handed down by Judge Keenan Johnson said one of the teenage victims recalled O’Connor saying “his family owned Collooney and Ballisodare”. O’Connor told court that banks had withdrawn funding for three Beldare projects as a result of the incident and indicated the case had “catastrophic consequences” for his company. He employed 100 people.
