Ammonia thrower at pro-Palestinian protest still not arrested, bought bottle nearby

October 28, 2024

Amsterdam — The police are still looking for the man who threw a bottle with ammonia at a police riot unit in May, during a pro-Palestinian demonstration in Amsterdam. The bottle was believed to have been bought shortly before the protest at a nearby supermarket on the Nieuwezijds Voorburgwal, according to Opsporing Verzocht [Investigation Requested].

During the protest in central Amsterdam, a police officer got the liquid on his face, and as a result, could not see. He was treated at the hospital. Other riot police developed serious breathing problems or had to vomit.

Using the bottle, the police have determined where it may have come from. The investigation reveals that a half hour prior to the incident, four bottles were purchased at the Albert Heijn [supermarket] on the Nieuwzijds Voorburgwal opposite the Royal Palace. But police have not been able to determine who purchased the bottles.

In Opsporing Verzocht, images were shown in which a man can be seen throwing the bottle from the crowd. They were earlier shared by police.

The incident was on May 8. Earlier in the day, there was a demonstration in and near buildings of the University of Amsterdam on the Binnengasthuis Grounds. When that concluded, some of the demonstrators moved to the Rodin, where there was another clash with police.
