A senior police officer warned on Tuesday of calls for more riots in Amsterdam after dozens of people armed with sticks and firecrackers set fire to a tram on Monday night and the city grapples with tensions following last week’s violence. targeting fans of an Israeli football club.

Olivier Dutilh, of the Amsterdam police force, told a court hearing that “we have signals that there are requests for similar disturbances’ in the west of the city.

The streets in the area were relatively calm at nightfall and the security presence was light.

Amsterdam’s mayor, police chief and top prosecutor released a report Monday outlining what happened last week, including new details about the actions of Maccabi Tel Aviv fans ahead of the Maccabi Tel Aviv-Ajax soccer match.

Local authorities have decided not to ban the game, but have beefed up security. Local authorities banned pro-Palestinian demonstrators from gathering outside the stadium.

The day before the game, authorities reported incidents and saw social media posts threatening Maccabi fans.

At about midnight, Israeli fans broke a Palestinian flag on a building in the city center and several of them took off their belts and attacked a taxi, the document said.

Taxi drivers tried to mobilize online in response and focused on a casino where about 400 Israeli fans were gathered. The police mobilized to avoid a major confrontation.

On the morning of the match, authorities were “particularly concerned about Maccabi fans and the reaction of taxi drivers,” the document said.

Amsterdam Mayor Femke Halsema asked the Israeli ambassador for officials in Israel to clarify “that this is a sporting event and should not be mixed with politics.”

In the afternoon, social media posts intensified and anti-Semitic terms were used.

After Ajax’s 5-0 win over Maccabi, parts of a large group of Maccabi supporters “run around with sticks destroying things”, the document said.

There were also “robbers, moving in small groups on foot, scooter or car, quickly attacking Maccabi fans before disappearing,” according to the City Hall timeline.

The police chief said those incidents had “an anti-Semitic character – there is talk of a hunt for Jews and people are being asked about their nationality”. Then there were rumors of missing persons and hostage-taking, which turned out to be unfounded.

Police said Monday’s fire was quickly extinguished and riot officers cleared the square. Images online showed people destroying property and setting off firecrackers.

A police vehicle was later torched on a nearby street and police said they suspected arson.

Police said it was unclear who started the unrest and whether it was related to what happened last week. Some rioters could be heard in videos shared on social media using insults against the Jewish people.

The police said that detained three suspects and appealed for witnesses, including the attack on a cyclist who was beaten as he drove past the disturbances.

Police noted the tense atmosphere in the city as five people were treated in hospital and dozens were detained following the football match on Thursday.

Youths on scooters and on foot went in search of Israeli fans, punching and kicking them and then running to evade police, according to Amsterdam’s mayor.

Prime Minister Dick Schoof met with members of Amsterdam’s Jewish community on Tuesday to discuss anti-Semitism in the wake of the violence.

Reports of anti-Semitic speech, vandalism and violence have been on the rise in Europe since the start of the Gaza war.

A total of eight people are in custody in the investigation into last week’s violence, aged between 16 and 37, in Amsterdam and nearby cities, according to police.

Police said they identified more than 170 witnesses and took forensic evidence from dozens. The prime minister said he was also looking into videos posted on social media.

The mayor banned all demonstrations in the city and declared several parts of Amsterdam risk zones where the police can stop and control anyone.

Dozens of people were detained on Sunday for taking part in a pro-Palestinian demonstration in central Amsterdam that was banned.

A small demonstration was broken up by police outside Amsterdam City Hall on Tuesday during a debate about the unrest, Dutch broadcaster NOS reported.
