The police in Amsterdam were holding four suspects on Saturday in connection with an investigation into what the city authorities described as antisemitic attacks on Israeli soccer fans in the Dutch capital this past week, a police spokeswoman said.

The police initially detained 62 people around the attacks, which unfolded over two days on Thursday and Friday. On Thursday, the tension and violence simmered around a match between Ajax, a Dutch team, and Maccabi Tel Aviv, an Israeli team.

Videos showed Israeli fans shouting anti-Arab chants on their way to the match as the police escorted them near Amsterdam’s central train station to help ensure their safety amid anger over the war in Gaza. One of the chants said: “Why is there no school in Gaza? There are no children left there.”

At the stadium, riot police units and mounted officers kept pro-Palestinian groups and Israeli fans apart.

Most of the 62 who were initially detained were quickly released, while four remained in custody on Saturday, all suspected of public violence, according to Marijke Stor, a Dutch police spokeswoman. One of the four is a 26-year-old who was arrested on Friday after the police identified him from CCTV footage, she said.

“If people are released, it doesn’t mean they are no longer a suspect,” Ms. Stor said. “Other arrests can still be made, of course, because the investigation is still ongoing,” she added. Prosecutors have not charged anyone, she said.
