A man has been arrested on suspicion of carrying out a paramilitary-style attack, police said.
The 34-year-old was arrested under the Terrorism Act and is now being questioned over the “brutal attack” in Londonderry last month, the Police Service of Northern Ireland (PSNI) said.
A man in his fifties was shot in both legs after answering the door to a group of masked men in dark clothing, the force said.
It happened in the Brandywell Road area of the city at around 8.30pm on Friday October 5.
The suspect was arrested in the Ballymagroarty area on Thursday and taken to Musgrave police station.
Detective Inspector Heaton said: “We are committed to tackling all types of violence linked to paramilitaries and this arrest comes after a brutal paramilitary-style attack on a man in the Creggan area last month.
“Paramilitaries are a blight on society and do not represent the interests of the community. They often claim that they are protecting their communities but in reality they seek to exert their control for their own selfish gains.”
