http://www.bbc.co.uk/news/uk-northern-ireland-34645385A group of teenage schoolchildren from Northern Ireland have been attacked and injured by a gang of hooded youths during a school trip to Manchester.
Fourteen pupils from Portadown College, County Armagh, aged between 14 and 17, were assaulted on Sunday.
Five were treated in hospital but the school's principal said none of them was seriously injured.
Greater Manchester Police described the incident as a 'brutal' attack.
Insp Fahar Zaman said: "This was an unprovoked attack on some young people who were visiting our city.
"It is very disappointing that the memories they are left with will be of this brutal attack.
"We are working with the Trafford Centre to gather evidence and we are following some positive lines of enquiry to find those responsible."
He said said police were treating the matter "very seriously" and were appealing for witnesses to get in touch.
The students had travelled to the city as part of the school's annual trip to attend football matches in Manchester.
'Traumatic'
Craig, one of the pupils who witnessed the assaults, told the BBC that "at least 40" local youths attacked his school group as they left a shopping centre.
