Saoradh's Derry headquarters raided by PSNI as part of Operation Arbacia
PSNI Crime Operations Assistant Chief Constable Barbara Gray said: "Detectives from Police service of Northern ireland's Investigation Unit have today searched properties in Belfast, Dungannon, Newry and Derry/Londonderry in connection with an ongoing investigation into the activities of the New IRA.
"The properties were searched under TACT legislation as part of Operation Arbacia, a community safety operation."
The search at Junior McDaid House follows what Saoradh branded the 'MI5-led' arrest of several party members earlier this week.
A spokesperson said: "Saoradh is not a proscribed organisation, we have as our means political agitation, mobilisation and grassroots activism. Since our formation in 2016 we have grown and we continue to grow."
