According to the news, what happened to the couple?

Police in Northern Ireland have apologised to a couple for mistakenly arresting them moments before their wedding ceremony was due to begin. The Irish groom, his Chinese bride and their guests were detained on suspicion that the marriage was fictitious for immigration purposes. Here’s our Northern Ireland reporter Andy Martin.
    The groom knew immediately that something was wrong when the registrar at Derry’s Guildhall unexpectedly claimed that there was unfinished paperwork just before the ceremony began. He and his fiancee were led into an adjoining room and arrested by detectives. They were taken to a nearby police station, locked in separate cells and dressed in paper forensic overalls. Although the police have apologised, that’s not enough for Mr McElwee. The couple were married 24 hours later, but say the magic had already been taken out of their big day.
