Police said they had used water cannon to disperse activists blocking a major road in the city, and arrested "a total of 1,579 people ... 40 of whom will be prosecuted" on charges including vandalism.

Anticipating the water cannon, some wore swimsuits or carried umbrellas as they sat in protest across the A12 motorway, holding banners and signs.

But Saturday saw the highest number of people arrested at a protest yet, according to Dutch news agency ANP.

"We're going to stay here until they drag us away," said postgraduate student Anne Kerevers, 31.

Van Houten posted a video on Instagram showing herself wearing a red poncho, getting drenched from a water cannon. (editors note: The Instragram post won't show in the US, so we're linking to another article on it). 

ANP reported that she was arrested and later allowed to return home, but did not specify whether she was among those who will be prosecuted.
