Eleven men are expected in court charged in connection with a police raid at a bar in the Tiger's Bay area of north Belfast last Thursday.
The men were arrested last Thursday
The men are charged with helping to set up a meeting supporting a banned group. Seven are charged with wearing clothes associated with a terrorist group.
It is understood the illegal groups are the loyalist Ulster Defence Association and the Ulster Freedom Fighters.
The 11 men are due to appear at Belfast Magistrates Court on Monday.
The charges relate to a police search at the Alexandra Bar on Thursday evening.
Six other men and a woman who were also being questioned have been released, pending reports to the Public Prosecution Service.
The UFF is part of the Ulster Defence Association, set up as its "military wing" before the UDA was proscribed.
