The 30-year-old victim is recovering in hospital
PSNI detectives investigating a paramilitary style shooting on Friday night have arrested a man.
The incident happened in the Newtownabbey area, north of Belfast.
The suspect, aged 30, was arrested on Saturday night under the Terrorism Act.
Detective Inspector Conor McStravick said: "The 30-year-old victim, who was shot in the knee in Bawnmore Park, is thankfully recovering well in hospital.
"Officers examining the scene of the shooting have discovered that a second shot may have been fired, with the bullet striking the perimeter fence at the local youth club.
"This shooting occurred at 7.30pm, a time when children could easily have been playing at the youth club.
"To my mind, this serves to underline the mindlessness and recklessness of those responsible."
