Three people have been arrested after gangs of Protestant and Catholic youths clashed with each other and the police at Belfast's Christmas lights switch-on.

The three arrested - a 19-year-old man, a 17-year-old boy and a 14-year-old girl - were released pending reports to prosecutors.

Shop windows were broken and cars were vandalised during the disturbances in the city centre. Police said there were no reports of any injuries.

The area was packed with families for the annual event outside the City Hall, which this year had cartoon character Bob the Builder as guest of honour.

A spokeswoman for Belfast City Council criticised those responsible for the trouble.

"It's very disappointing that a small minority of youths were intent on causing trouble at what was a fun family event for the city," she said.

"There is always a fantastic atmosphere in Belfast during the annual Christmas lights switch-on and it was great to see so many people enjoying the entertainment at City Hall, and helping to kick off the city's festive season.

"At a time when Belfast is buzzing and attracting tourists and shoppers, this was a great opportunity to showcase all that is good about our city.

"Instead a very small minority have detracted from the overall success of tonight's event, which saw hundreds of people come to Belfast to enjoy an evening of fun family entertainment."
