James Reid, 23, with an address at Homelawn Avenue in Tallaght has been charged with producing a knife during the course of a dispute.
He is the fourth person to be charged in the case.
Judge John O'Neill granted Mr Reid bail, subject to strict conditions, which include that he stay away from Tallaght, surrender his passport and sign on three times weekly at a garda station.
He also made an undertaking not make contact with the others charged.
