A 29-year-old man remained in police custody last night after a stabbing in north Belfast.
Police and paramedics were called to Havana Walk in the Ardoyne area at around 4pm yesterday.
A man in his 20s was taken to the Royal Victoria Hospital for treatment to stab wounds, which are not believed to be life-threatening.
A 29-year-old was arrested in connection with the attack.
"Enquiries are at an early stage and there are no further details at present," a PSNI spokesperson said.
SDLP councillor Paul McCusker said he was "liaising with police" following the incident.
"Ambulance service currently treating the male who was injured and a part of the area has been cordoned off," he wrote on Twitter.
"Very worrying for residents to witness this and on my way to the scene."
