A man and a teenager are being questioned today about a major riot in north Belfast that left more than 100 police officers injured.
The security forces came under heavy attack from a nationalist mob after trouble flared around a disputed Orange Order parade through the Ardoyne district on July 12th.
Blast and petrol bombs were hurled at police and soldiers after marchers passed along the route.
The Police Service of Northern Ireland confirmed today they had detained a man (22) and a 15-year-old teenager. The pair were arrested in the Old Park area of the city and taken to be interviewed about public order offences.
Two journalists and members of the public were also wounded. With CCTV footage capturing the disturbances, questions had been asked about why arrests were not made immediately.
