A couple and their son have left Dublin and gone into hiding after they were allegedly falsely imprisoned in their own home by a gang of seven men.
Declan Duffy (43) is the alleged "joint leader" of this gang, a senior garda claimed to a court.
Mr Duffy, with his co-accused Daniel Kane (27) and Christopher Maguire (37), of Dun Emer Place in Lusk, appeared before Cloverhill District Court charged with three counts of false imprisonment at The Towers, Garters Lane in Saggart.
Mr Duffy, from Hannover Street West in Dublin and Mr Kane, of Hollycourt in Ballybrack, are also charged with violent disorder.
Gardai objected to bail, saying they feared witnesses may be intimidated.
Detective Inspector Colm O'Malley said gardai responded to a 999 call at 12.10pm on June 9 last where they met a man who appeared to have been "viciously assaulted".
He was rushed to Tallaght Hospital suffering a fractured skull and eye socket and a broken arm.
Insp O'Malley said another man, whose ear was cut, then approached gardai.
He claimed to gardai he had been taken "against his will" from Rathcoole by seven men and driven to his apartment in Saggart.
The man then alleged he, his wife and their son were falsely imprisoned in their home for 40 minutes.
Insp O'Malley claimed the couple are "afraid" and living at an unknown location.
He claimed Mr Duffy is the "joint leader" of this gang with another man.
Insp O'Malley also alleged that if given bail, Mr Duffy would be "in a position to influence others in this group".
Defence lawyers said the men were willing to abide by any bail conditions.
Judge Victor Blake remanded Mr Maguire and Mr Kane in custody with consent to cash bail.
In relation to Mr Duffy, Judge Blake refused bail and remanded him in custody to a date in January.
