Solicitor Michael Lynn has been charged with in relation to a fraud investigation by gardai after being extradited from Brazil.
A plane carrying Mr Lynn touched down in Dublin at 1.22pm from Brazil via Frankfurt.
He was then brought to Ballymun garda station where he has since been charged by gardai and was brought before a special sitting of the Dublin District Court at 4pm.
A garda spokesman said: "Gardaí from the Garda National Economic Crime Bureau have, today, charged a 49-year-old male, who has been extradited from Brazil, in connection with a number of fraud incidents from 2006 and 2007."
Former solicitor Michael Lynn was wanted in connection with alleged offences linked to the collapse of his property business.
The 50-year-old’s property business had debts of €80m when it collapsed.
He has been in prison in Brazil for the last five years while fighting extradition back to Ireland.
Last week he lost a High Court action seeking a declaration that the Director of Public Prosecutions that the time he spent in prison in Brazil would be offset against any prison sentence imposed on him in Ireland.
Meanwhile, Justice Minister Charlie Flanagan said today; "I note the return of Mr Lynn. This is now clearly a matter for the courts, and it would be inappropriate for me to make any further comment."
