Over 100 people have been arrested as part of a major police crackdown on unionist rioters in Northern Ireland.

The PSNI said 106 people were detained by detectives from the Operation Titan team investigating serious disorder that flared in parts of north and east Belfast on 12 July.

A total of 77 people have been charged with a range of offences linked to the trouble and a further ten people have been reported to the Public Prosecution Service.

Detective Superintendent Sean Wright said: "It is vital that we all send out a message to those involved in public disorder that such behaviour will not be tolerated. Those who break the law must face consequences for their actions.

"They will be dealt with appropriately and proportionately through the criminal justice system."

OVer 40 police officers were injured as they enforced a ruling by the Parades Commission adjudication body, which prevented Orangemen from marching on a contested stretch of road in north Belfast.

There were also violent clashes after Orange Order parades passed a sectarian flashpoint in the lower Newtownards Road area of east Belfast last month.

The PSNI said the Operation Titan detectives were investigating a range of offences including the attempted murder of police officers, blast bomb attacks on police, hi-jackings, rioting, breaches of the Parades Commission determination and unlawful protests.

They have appealed for anyone with information to come forward and have re-released images of 17 men they are keen to speak to.

Mr Wright added: "I would ask anyone who believes one of the images is of them to contact us immediately in order to help us with our inquiries."

Last week, the Police Federation, which represents rank and file officers, claimed there had been an increase in the number of officers seeking psychological treatment after being caught up in violence.

Federation chairman Terry Spence said almost 500 policemen and women had been hurt as a result of last year's marching season, disorder linked to the Union flag protests earlier this year and violence this summer.

Officers also still face a severe threat from dissident republicans.

The union is pressing for 1,000 extra officers to be recruited to the force, which currently stands at around 7,000.
