Ajax-Celtic disorder: Dutch police arrest 44 people
Dutch Police have arrested 44 people - 28 of them Scots - after violence flared in Amsterdam before Celtic's Champions League game against Ajax.
Six Celtic fans have been charged with being violent in public and are due to appear before a judge on Friday.
A further 12 have been freed after paying fines of up to 500 euros and 10 were freed without charge.
Dutch Police said eight officers were hurt after being attacked with bottles and sticks by Celtic fans.
Some of the disorder was said by police to have been sparked by Dutch fans getting hold of a flag which Celtic supporters had been holding.
Celtic Football Club said it was aware that a number of individuals had been detained.
In a statement, the club added: "We are not clear if they have any formal association with the club, however, we will be liaising with the local authorities in Amsterdam, our own police and the British Consulate in order to fully understand events.
"We would stress that 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 fully.
"There is no question that Celtic supporters have been subjected to a high degree of provocation."
The club added that the "overwhelming majority" of its supporters behaved impeccably.
Police Scotland said they were aware of disorder in Amsterdam and they would work with Dutch colleagues to identify anyone involved in the trouble.
On Wednesday night, Dutch police said a number of people had been arrested following incidents of disorder in Amsterdam, particularly in Dam Square, where Celtic fans had gathered.
A Dutch police spokesman said: "At the end of the afternoon a large group of Celtic supporters attacked police officers in plain clothes.
"Eight were injured and one was knocked unconscious. A few of them had broken noses and needed stitches above their eyebrows and on their lips.
"Bottles and sticks were used in the attack which came out of nowhere."
A spokeswoman for Police Scotland said: "As is normal practice during international tournaments, Police Scotland has deployed officers to Amsterdam for the Ajax v Celtic match, and we have been working closely with Dutch police and authorities in relation to security at this fixture.
"We have been made aware of some disorder in Amsterdam... with a number of Celtic fans having been arrested.
"We will continue to work with our Dutch colleagues to identify anyone responsible for carrying out acts of disorder."
Before the Champions League game, which Celtic lost 1-0, the Scottish club urged its fans to be "extra vigilant" after a group of supporters were attacked in a city centre bar.
It was reported that about 50 Celtic fans were in the Old Sailor Cafe in Amsterdam when they were attacked by a group of hooded men on Tuesday night.
There were no serious injuries and a number of people were arrested.
The attack followed trouble last month when a group of Ajax fans ripped up and threw seats at police and home fans as the teams played in Glasgow.
Uefa opened disciplinary proceedings against the Dutch club after the clashes with police and stewards at Parkhead, during a match which the home side won 2-1.
