Operations at a Belfast bar have been frozen as part of an investigation by the Serious Organised Crime Agency (Soca).
An order was granted on Tuesday to freeze 11 properties including Club Mono in Ann Street as well as houses in Belfast, Lisburn and Holywood.
Soca has also searched two properties in Holywood and Lisburn in relation to the same investigation.
Items were seized under the Proceeds of Crime Act.
The property freezing order was granted in the High Court in Belfast involving property held by Gerald and Geraldine McCann of Seapark Lane in Holywood; Joseph and Lorraine Corr of Monaville Avenue in Lisburn; Gerald Anthony McCann of Seahill Drive in Holywood; Gerard Thomas Corr of Lagmore Dale in Dunmurry; Francis McComb of Lagmore Downs in Dunmurry; and Susan Patricia Osbourne of Royal Mews in Dunmurry.
The alleged criminality includes mortgage fraud, Soca confirmed.
Gerald Robert McCann, 40, of Seapark Lane, Holywood, was extradited to Spain to face drugs charges on December 30.
