An Apprentice Boys march in Derry this afternoon has passed off without incident and has been described by the PSNI as one of the most peaceful in more than ten years.
Only four arrests were made as an estimated 10,000 Apprentice Boys and 120 bands took part in the main demonstration which commemorates the 1688 Siege of Derry.
Supt Johnny McCarroll said: "It was very successful - I think it was one of the most peaceful parades that I have seen in 15 years of policing."
"I am very pleased for the city."
Two people were arrested for drunkenness while another pair were arrested for disorderly behaviour.
Police also said that seven bands would be reported to the Apprentice Boys organisation for behaving in a "deliberately provocative manner".
Earlier, rival groups of loyalists and nationalists exchanged taunts during the parade.
Local SDLP Councillor Colum Eastwood described the sectarian chants from band members in Derry today as 'shameful and totally disrespectful'.
Cllr Eastwood said he was glad the parade was peaceful but added: "I was totally disgusted to watch on as band members and supporters chanted sectarian slogans.
"These chants were used to incite hatred and provoke nationalists.
"They were totally uncalled for and in my opinion were totally disrespectful to the citizens of Derry.
"The town has come to a standstill today as most shops closed their doors. To be treated with such contempt by band members and supporters is a grave insult to the nationalist community."
Cllr Eastwood appealed to everybody to remain calm for the remainder of the day.
Police praised the co-operation of the Apprentice Boys, the Bogside Residents` Group and Chamber of Commerce during today's event.
