The Dutch police announced today that they are investigating 45 people suspected, nine of them identified and arrested, of the acts of violence on November 7th, on the sidelines of the Israeli football team Maccabi Tel Aviv's game in Amsterdam.
The number of suspects is expected to increase "in part based on analysis of a large number of images", police added.
"Due to the seriousness of the infractions, but also due to their social impact, we immediately created a special investigation team," explained police chief Janny Knol, quoted in the press release.
Police are "investigating all crimes committed before and after the game", said Janny Knol, in the wake of the violence that rocked the Dutch capital, leading to several demonstrations and a near collapse of the governing coalition.
According to police, there was high tension before last week's football match between Maccabi Tel Aviv and Ajax, in the Europa League. Israeli fans chanted anti-Arab slogans, vandalized a taxi and burned a Palestinian flag in Amsterdam's main square.
After the game, Israeli fans were attacked by men on scooters. Police said the attackers had been encouraged on social media to attack Jews.
Five Maccabi fans had to receive hospital treatment, a fact that provoked outrage from Western leaders.
Dutch and Israeli authorities condemned the attacks as "anti-Semitic" and called for the perpetrators to be swiftly punished.
"It goes without saying, but I think it's worth highlighting, that we are focused on all crimes committed before and after the game, regardless of the identity of the perpetrator or victim," Knoll highlighted.
Muslim rights groups condemned anti-Semitism but emphasized that the violence in Amsterdam was not one-sided.
Last week, Prime Minister Dick Schoof blamed the violence on people of "immigrant backgrounds."
On Friday night, Dick Schoof's right-wing coalition government narrowly avoided collapse after the Moroccan-born Dutch Secretary of State for Benefits and Customs, Nora Achahbar, resigned in protest at what she said were comments racist remarks made by one of his cabinet colleagues, following the violence against Israeli fans.
The head of government vehemently denied the allegations and tried to calm concerns after a crisis meeting.
