six Scots have appeared in court in Amsterdam charged with acts of violence against police officers following clashes before Celtic's Champions League match against Ajax.

Dutch police said two of the men would be held in custody until they are brought to trial before a judge on November 21. The other four were due to be released until that date, although prosecutors are expected to appeal that decision.

Authorities in Amsterdam only release the first name and first initial of the surname of those charged with a crime. The six fans were named as Thomas K, aged 30, Damian D, 23, Jozef M, 20, Paidrag M, 28, Andrew V, 21, and 49-year-old John Q.

They were charged with acts of violence against police officers in a public space.

The development came as Uefa confirmed it will take action against Ajax over an offensive anti-Catholic banner displayed during the game in the Amsterdam Arena.

The European football ruling body said disciplinary proceedings had been opened against the Dutch club over "discriminatory behaviour of their fans". The case will be heard on Tuesday.

Uefa opened disciplinary proceedings against Ajax last month after clashes with police and stewards at Parkhead during the initial fixture, which the home side won 2-1. A disciplinary case relating to that match is to be heard on November 21.

Celtic boss Neil Lennon said he was "not surprised" there was trouble in Amsterdam ahead of the game, which Celtic lost 1-0, given the behaviour of the Dutch club's fans in Glasgow last month.

He said: "I am disappointed but not surprised, looking at what happened at Celtic Park with the Ajax fans in terms of ripping up seats and throwing them at our supporters.

"If there are Celtic fans who have been out of order and they are members or season-ticket holders then the club will take appropriate action, obviously.

"If the club's reputation has been damaged I am disappointed with that, but Celtic fans, I think, are the best in the world.

"But I think there is a culture at Ajax. I think Man United fans and Man City fans had problems recently, so I don't think it is exclusive to Celtic.

"I am not going to point the finger at them [Celtic fans], because I don't know what the facts are, but our fans are exemplary.

"I have been here 13 years and everywhere they go, they have been an absolute credit to the club. They make a lot of friends wherever they go.

"Again, I don't have the facts in front of me, but I would say that if there was a reaction, there was immense provocation in the first place."

A Celtic spokesman said: "We have already been informed by Uefa's own security officer that he reported this matter together with photographic evidence.

"This is in addition to complaints submitted by Celtic supporters who are understandably deeply offended."

Twenty-eight Scots were among 44 people arrested following the clashes on Wednesday which left eight Dutch police officers injured. Dutch Police said that 22 of the Scots were released with fines of up to €500 (£417).

Celtic responded to claims from fans that they were poorly treated by opening an internal investigation and said the club will liaise with authorities in Amsterdam, Scottish police and the British Consulate.

A club statement said: "There is no excuse for any form of violent conduct. In addition, we have received numerous complaints from Celtic supporters in relation to their treatment in Amsterdam, which we will also investigate."
