FIVE Celtic fans found guilty of ­violent disorder against Dutch ­police could have to wait a year for an appeal to be heard.

Andy Vance, Padraig Mullen, Damian Dobbin, Thomas Kennedy and Joseph McPherson were all convicted at Amsterdam District Court of committing violence in a public space.

All five deny the charges but were given sentences of between four weeks and two months in jail.

They were all released pending an appeal and are understood to have travelled home yesterday.

A sixth fan accused of the same offence was found not guilty.

The men were arrested when trouble broke out in the city's Dam Square before Celtic's Champions League match against Ajax on November 6.

Celtic said it could not comment on the men's cases.

However, officials confirmed the club's Dutch legal representative is working on behalf of other supporters' who have complained about their treatment.

In a statement, Celtic said: "We have received numerous written complaints from fans regarding their treatment in Amsterdam.

"The lawyer we have engaged is currently reviewing these in order to assess whether they can be taken further through the legal ­system in Holland.

"We believe these to be credible complaints, with substance and therefore deserve further investigation."

Dutch police said 28 people from Scotland were among a total of 44 arrested and that eight officers were injured.

Vance, from Blantyre, and Mullen, from Belfast, had been held in custody since they were arrested.

Dutch lawyer Christian Visser, who represented the six men, said he was disappointed by the judge's ruling.

Mr Visser said he will be appealing over the verdict but that the cases could take a long time to come back to court.

He added: "By the time we are back in court for the final hearing, it could easily be a year."

The judge awarded three police officers damages of 250 euro (£209), while another ­officer was awarded 500 euro (£420).
