Two teenagers have been arrested after police were attacked with petrol bombs during disorder in west Belfast on the Eleventh Night.
Police were attacked while on patrol in the interface area at Springfield Road near Lanark Way.
A number of people had gathered and a number of petrol bombs were thrown.
A 16-year-old male was arrested on suspicion of unlawful assembly and a 17-year-old male was arrested on suspicion of riotous behaviour.
Both have been released on bail pending further enquiries.
On Friday morning police discovered a suspicious object in the Springfield Road area.
The road has been closed and motorists are advised to seek alternative routes.
Police are also investigating complaints about various material, some of which was described as "distasteful", placed on bonfires.
A 52-year-old man was arrested and charged with offences including criminal damage and he is due to appear at Lisburn Magistrates Court next month.
As is normal procedure, the charges will be reviewed by the Public Prosecution Service.
PSNI Assistant Chief Constable Barbara Gray said that she was "relieved" that "we did not see a repeat of the violence we witnessed on our streets this time last year".
“There is also no doubt there have been challenges over the last week, not just for us a Police Service, but also for other public services," she said.
“In Belfast, we welcome the all-party working group to be established by Belfast City Council. Dialogue for next year must begin now.”
