England defender Maguire was found guilty of repeated bodily harm, attempted bribery, violence against public employees and insulting behaviour after his arrest in a brawl during which two police officers were assaulted.
He received a suspended prison sentence of 21 months and 10 days, but Manchester United said on Wednesday that Maguire had been granted a full retrial after appealing against the verdict.
“It was horrible. It’s not something I ever want to do again. I don’t wish it on anybody. It’s the first time I’d ever been inside a prison,” Maguire said of his two nights in custody.
Maguire said his younger sister Daisy had been attacked in a bar on the island by two men who drugged her, adding that when he tried to take her to hospital he was arrested.
