The man is suspected of carrying out an attack earlier this month.
A 51-year-old man has been arrested under the Terrorism Act by detectives from PSNI’s Terrorism Investigation Unit.
The man was arrested in the Creggan area of Derry on suspicion of carrying out a paramilitary style attack in the city on 5 October.
A seizure of a number of items as part of an ongoing investigation into dissident republican activity was also carried out following a search of a property on Thursday evening.
The suspect has been taken to Musgrave Serious Crime Suite for questioning.
Speaking about the arrest, Detective Inspector Heaton said: “This arrest comes after a vicious paramilitary style attack on a man in the Creggan area earlier this month.
“Paramilitary style attacks are barbaric and despite claims from the groups responsible that they are protecting their communities, they are only ever about people cementing their own status and control over their communities.
“We are committed to tackling all types of violence linked to paramilitaries and will continue to work in partnership with local agencies, residents and community representatives to keep people safe.”
