PSNI search operation in Strabane
Detectives investigating the activities of violent dissident republican terrorists have carried out a series of searches.
The operations took place in the Mourne Avenue, St Colman's Drive and Innisfree Gardens areas of Strabane yesterday.
Police said they were in connection with recent incidents across the Londonderry and Strabane area.
These included pipe bomb attacks in Melmount Villas, Strabane, earlier this month and in Drumrallagh in Strabane in July.
PSNI Detective Inspector Michael Winters said: "We are committed to disrupting the activities of these groups."
